Since we have a thread going for the 10 best, and there were so many mentions of ones people hated...I figured we might as well list 'em.  Most of the books I read were pretty good this year, but there were a couple of stinkers and disappointments:

Passion (Berkley Sensation) by Lisa Valdez. I thought this was going to be so good, but it didn't do anything for me.

Aiden's Charity (Breeds, Bk 11)  by Lora Leigh. I can't even remember why I didn't like this book, I usually like the breed books, but I only gave it 2 1/2 stars.

Blackmailed by Annmarie McKenna. I left a review there...'nuff said.

Cry No More by Linda Howard. I read it again this year hoping it would be better than the first time I read it...nope, hated it this time too!

MASTER OF PARADISE by Katherine O'Neal - Oh boy, was this ever baaaaad. It was a definite stinker.

Oath Of Seduction: Seducing Sharon  by Marly Chance - I left a review  - book's okay until an incident towards the end that had me boiling.

Private Party by Jami Alden - He wants her, he doesn't want her, back and forth until the end - very annoying. I reviewed this one too.

Then You Hide (Bullet Catchers, Bk 5) by Roxanne St. Claire - the annoying abrasive heroine with the vacuum cleaner mouth (see review there)

After the Night by Linda Howard. I love this author but I detest this book because of the way the "hero" continually mistreats the heroine.  This was another book I tried to re-read thinking maybe I'd like it better after a few years...nope.  The hero's still a jerk.

Kiss Me While I Sleep by Linda Howard. Is he going to kill her, is he going to let her live, blah, blah. Another unsuccessful attempt at a re-read.  I didn't like it anymore than I did the first time.

I wouldn't say that I read any "worst" books.  If they weren't good, I stopped reading them.

However, I did read a lot of so-so books.  All I can say is there are just too many to list.

BTW, I loved Passion, but I read that one when it first came out.  I hardly remember it now.

I also love Linda Howard and haven't been overly disappointed in any of her current books. 

I've read a lot of good books this year, but there were several duds.  We'll see if I can come up with 10.

Passion - Lisa Valdez   (ITA with Lynn - this book did NOTHING for me)
Delicious - Sherry Thomas (I don't get what all the fuss was about - I didn't even get halfway through)
The Lady's Tutor - Robin Shone
Fearless - Diana Palmer
Bad Boys Online - Erin McCarthy
In the Highlander's Bed - Cathy Maxwell
Highland Savage - Hannah Howell
Lessons of Desire - Madeline Hunter
Viking Unchained - Sandra Hill 
Damien - Jacquelyn Frank - Didn't finish this one either.  I was excited to get into a new series, but had no desire to try another one after this.  Ugh.

Michelle

Okay..I can do this!! : ) LOL. But I gotta get a pen and paper to write it all down, then copy it. I'll be back to add it all in!

I can't think of ten but I have one right of the bag

A Cedar Cove Christmas by Debbie Macomber. It was cringe-worthy. The characters' names, the plotline, etc are so corny. I am for corniness and such but she took it to the next level.

Just 10 is all I get? lol  Here goes:

Touched by Love - Tracy Garrett

MacKenzie's Mountain - Linda Howard

The Bride Sale - Candice Hern

Touch a Dark Wolf - Jennifer St Giles

Soldier Caged - Rebecca York

Highland Fling - Tess Mallory

Sarah's Child - Linda Howard

The Bartered Bride - Mary Jo Putney

First Born - Lindsay MacKenna

My Immortal Protector - Jen Holling

It's hard for me to remember bad or blah books.  I don't finish them and just forget them. 

Passion by Lisa Valdez   I also don't get what all the excitement was about.  It was boring and I barely finished it.

Blackmailed by Annmarie McKenna   One I hated enough to remember.  It was so bad on many levels.  No redeeming qualities at all.

Vampire Academy by Richelle Mead    Loved Storm Born so I bought this one.  Didn't finish.

Atlantis Rising by Alyssa Day    Struggled to finish and traded off the rest of the series without reading.

Killer Charms by Marianne Stillings   I love the humor in her books and thought this one had little to none.  Without that, was just a forgettable romantic suspense.

Casting Spells by Barbara Bretton   Enjoyed it all the way to the end.  Haven't forgiven her for the ending yet.

Tempted by Megan Hart    Loved, loved, loved Dirty and Broken.  Hated this one.  The h ended up with the wrong H.  Though I don't really care because I didn't like any of the characters anyway.

Wicked Pleasure by Lora Leigh  No chemistry, mechanical sex.  Ready to move on to other authors once I finish the Breeds series.  Maybe before if the next one of those is as lifeless as this book  was.

Double Jeopard by Rachel Bo   The two H's were immature and self-centered.  And a tad spineless.  The h was fighting their fights and supporting them financially.  Ick. 

Read a couple of books by Katie Macalister.  Can't remember the titles now.  She's definitely not for me.

edited to say it's a good thing for authors that we all have such diverse tastes.  Cry No More is one of my favorite reads of all time.

Rawhide Man - Diana Palmer - honestly can't believe I made it through this one

Dream Shadow - not horrendous but not super-great for being ellora's cave, more disappointing than 'bad'

Dark Seduction -  Brenda Joyce - not a bad story but not very romantic IMO until maybe towards the end but by then the woman was stupid

HOmefront Holiday - Jillian Hart - love inspired homecoming heroes 'grand finale' - way too much emphasis on the stupid kid in this one - nauseating..gag...

No Escape - shannon k butcher - more suspense and a crazed psycho - couldn't enjoy what romance there was due ot this..

Heaven and Earth, FAce the Fire - nora roberts - enjoyed the first book but didn't like either of the 2 women in these 2 - esp the 3rd book.

I tend not to finish books I dislike, and then I apparently banish them from my memory immediately, because I only have a few for this list:

Seeing Is Believing - Kate Austin - women's fiction with a touch of magical realism from the now defunct Harlequin NEXT line

sloppy writing and a big disappointment after enjoying another book by this author

Who Is Deborah? - Elise Title - contemporary gothic romance from the old Silhouette Shadows line

amnesia plot and a hero who was weird and scary

A Page Out of Life - Kathleen Reid - women's fiction about a scrapbooking group

More sloppy writing. I didn't finish this one. I was hoping it would be similar to Jennifer Chiaverini's quilting series, but no such luck.

Passion was responsible for several urky moments, but it's probably not the worst I've read this year.  Here's my top 10 list, and these are truly bad, stinkburger books, sorted from bad to worse:

#10 - Beyond Innocence  by Emma Holly.  I had such high hopes for this book, because Beyond Seduction was so good.  This thing was awful however.  Dragged on forever, and got more stupid as it went.

#9 - Heart of a Lion by Hillary Fields.  A 300+ page joke.  And not even a good one:P  Best thing I can say about it is I finished it.  Barely. 

#8 - Tempting by Hope Tarr.  Just bad:P

#7 - The Buccaneer  by Donna Fletcher.  This one was eww from start to finish.  I don't really get what anyone sees in Donna Fletcher, to be honest.  I didn't really even care much for Irish Devil, but it was pretty good compared to this one.

#6 - Someone Irresistible by Adele Ashworth.  Probably the record holder for the slowest plot in print.  Hated it.

#5 - Night of Sin by Julia Ross.  Tragically, epically bad.  It actually destroys brain cells.

#4 - The Seduction by Laura Lee Guhrke.  Bought it from half.com & hated myself for it:P

#3 - The Scottish Companion by Karen Ranney.  So bad it actually damaged my retinas.

#2 - Uncommon Vows by Mary Jo Putney.  Uncommonly stupid.  I'd have rather had voluntary dental surgery.

#1 - The Light in the Darkness by Ellen Fisher.  This one goes on my epic list of the top 5 worst books I have ever read.  It may possibly be #1 on that list as well.

Oh... and honorable mentions go to:

Midsummer Moon by Laura Kinsale

Heheh - and there are two of my keepers on someone's list here. ;-)

I'm another who doesn't usually finish the really bad ones or remember them, but Fearless by Diana Palmer is way up there. A new low, even for her. Collision by Margaret Pargeter.  Dark Rival by Brenda Joyce. The latest by Samantha James, can't even remember the title, it was so boring.

I found 10:

Christmas Cards from the Edge :: Naomi Neale, Jennifer Ashley, Lisa Cach - so boring.

This Year's Christmas Present :: Nina Bangs, Dara Joy, Sandra Hill - boring

A Most Unsuitable Groom by Kasey Michaels- couldn't finish

A Sprinkle of Fairy Dust :: Marylyle Rogers, Elaine Crawford, Elizabeth Bevarly, Maggie Shayne - I didn't care for it.

Highlander in Disguise :: Julia London - finished but wasn't very good

Highlander Unbound :: Julia London - finished but wasn't very good

Where the Heart Leads: A Cynster Novel :: Stephanie Laurens - not all that good

The Vampire Queen's Servant by Joey Hill -finished it but didn't like it

Kiss and Tell (Bloodmates, Bk 1) :: Sandy Lynn -completely juvenile garbage

Training to Pleasure Author: Julian Masters - never finished.  not for me.

What Price Love? (Cynster, Book 13) by Stephanie Laurens - way too wordy, a chore to finish

I forgot Fallen by Erin McCarthy and Let Sleeping Rogues Lie by Sabrina Jeffries, which fall more in the category of "Not utterly terrible, but really disappointing."

Willa - I couldn't even finish Fallen.

there are about 6 books in this thread that I thought was pretty darn good. One is an all-time favorite that I must have read about 8 times.

Anyhoo, my Worst Reads this yr

1. Untamed - Hope Tarr ~ D+
   
2. Dark Moonless Night HP — Anne Mather ~ D 
3. First Love, Wild Love — Janelle Taylor ~ DNF
4. Rosehaven — Coulter ~ F/DNF
5. Wolf Tales III — Kate Douglas ~ F
6. Wife Against Her Will (HP # 2544) — Sara Craven ~ D
   
7. Blackmail HP # 517 - Penny Jordan ~ D
   
8. Wolfen - Madelaine Montague ~ D
9. The Tycoon’s Pregnant Mistress - Banks ~ D+
   
10. Savage Betrayal - Lynne Graham ~ F

I have a few keepers on this thread and a few I didn't mind as well, but for what it's worth here are some of mine in no particular order:

Breaking Dawn- Stephanie Myer- I liked the other books; they have their flaws, but they are good stories.  The conclusion was beyond wretched.

Dead After Dark- Sherilyn Kenyon, JR Ward- I read only the first two stories.  Kenyon's was awful, and a disappoinment, because it slighted a much loved character who deserved his own book.  Ward's entry was disturbing and creepy and not in a good way.

Kiss of Crimson-Lara Adrian- I may be the only person who hated this book.  Possibly it was because the heroine, in addition to being silly, was a vet who didn't actually know how to practice Veterinary Medicine?

Beyond the Highland Mist- Karen Marie Morning- It's as well that I read this after I'd read a few others.  If I'd read it first, nothing could have induced  me to pick up another.  It had two fatal flaws for me, stupid flat characters and absurd plot devices

Mr Cavendish, I Presume- Julia Quinn- I might have liked this book.  I had a fondness for both the hero and the heroine as characters, but it was so frustrating to read essentially a retread of The Lost Duke of Wyndham, when that book itself was only okay that this earns a spot on my list.

Devil May Cry- Sherilyn Kenyon- The 1100 year old heroine had never had an orgasm...really.

The Inheritance- Joan Johnston- Not awful, really, just very dated and not aging well at all. 

What does DNF mean?

I thought "did not finish", but I could be wrong about that:P

I thought "did not finish", but I could be wrong about that

That's what it means when I use it.

I don't think I have ten but these were my big stinkers of the year:

-Anything written by Jacquelyn Frank (seriously after Jacob these went down hill) Damien, Noah etc.

-The Accidental Vampire by Lynsay Sands, huh? is all I can say

-To Wed a Wicked Prince by Jane Feather

-Outsider by Diana Palmer (eww, just eww)

-In the Presence of Horses by Barbara Dimmick

-Secrets of Surrender by Madeline Hunter

I have a bad habit of reading anything I start even if I hate it. I get really OCD like that.

I don't keep track of my DNF but lets see what I can come up with

1. Dead After Dark by Sherrilyn Kenyon, J.R. Ward, Susan Squires, and Dianna Love
2. Riding Wild by Jaci Burton
3. Treasure Trail by Various (m/m pirate stories...omg it was so bad)
4. Kiss of Fire by Deborah Cooke
5. Dark Sentinel by Melissa Lopez
6. Midnight Reborn by D. McEntire DNF
7. A Knight Well Spent by Jackie Ivie DNF

thats all I can think of

Susan and Willa--I totally agree with you about Fallen. I didn't get very far in it before I lost interest. I can't remember many bad books but I do know that I didn't finish Dark Prince by Christine Feehan ( and I didn't bother with any of the others in that series) or Nightkeepers by Jessica Andersen--I still have it, may finish it someday. I know I'm in the minority but I couldn't really get into the Sookie Stackhouse books either.

DNF = did not finish

I DNF A Knight Well Spent by Jackie Ivie  also, mostly because it was boring, not b/c it was necessarily very bad
