I have recently been wanting to expand my lists of paranormal to young adults.  My only hang up with reading young adult is the teenage angst and immaturity.  Some people have mentioned several authors to me. I was wanting opinions if the series would be worth dwelving into.  

Kristin Cast: House of Night

Rachel Vincent: Soul Screamers

Kelley Armstrong

Richelle Mead: Vampire Academy 

Rachel Hawthorne: Dark Guardians.

Other authors you would care to mention would be great.

Jamie,

Some other ones I like is Sophie Jordan's Dragon series

Kim Harrison has a good YA series

Carolyn MacCullough Once a Witch and Always a Witch

Rachel Hawkins Hex Hall series

Holly Black White Cat

Unearthly Cynthia Hand

Alyxandra Harvey

Rachel Caine Morganville Vampire

Melissa De La Cruz - Bllue Blood Vampire series

Jenna Black Fariewalker series - love this series

Well there is a few more for you

I can't read them. I couldn't even get through Twilight.

I'd suggest

Carrie Vaughn's     Jennifer Scales

Cassandra Clare's    Mortal Instruments

Kim Harrison's    

Rachel Caine's  Morganville Vampires

Tate Halloway's    Vampire Princess

Jenna Black's Fariewalker Series

I got disgusted with House of Night early on, because I felt they were WAY TOO MATURE for the genre. And Gave up on them after about book 5 because they remained Too Mature AND got bogged down with TOO MUCH TEEN ANGST.

Well If you don't want a lot of teen angst do not read PC. & Kristin Cast's House of Night Series. It is overloaded with angst, drama, and bad southern or teen slang. She says she brought on Kristen to help her with the teen slang but I think she should have gotten someone else because the slang in this book is super annoying. I'm currently caught up except for the spinoffs for the series and I am to the point where I just don't want to read it anymore. I felt like burning the last book only I borrowed it from the library and they frown on that kind of stuff! I'll also have to agree with Nancy on the fact that she throws way to mature of subject matters in there for ya like in the first book one of the girl characters was witnessed giving a male character a BJ and they get more graphic after that. I just don't think teens need to be reading about that even though they might be experimenting with sex. And the characters are way to immature to be experimenting with sex but she writes them like they are way mature when they are not. Almost like its written by a 12 yr old who thinks she's 30.

I liked twilight but I read it when I was 20 right around the time when it first came out and It was my first real step into paranormal. I'd only read the classics before it so I think that might make me biased. I find I compare other books to it now and find it little lacking in writing style.

I've not read the Rachel Hawthorne series but out of the ones you listed I'd rate them angst and annoyingness like this: With Richelle mead being the best and Kristen cast the worst

Richelle Mead: Vampire Academy - I loved this series though I was disappointed with Rose's behavior in either the last or second to last one.

Kelley Armstrong - strong series that spins off into another series. If you like her adult series you should like this one.

Rachel Vincent: Soul Screamers

Kristin Cast: House of Night

I probably would not recommend the house of night series to anyone over 18.

I'll have to second Alice's list for Sophie Jordan's Dragon series, Jenna Black Fariewalker series, Anything by Holly Black. However Alice I got tired of the Blue Bloods Series its overloaded with drama now too. Also her new adult series wasn't that great either.

I'll second Nancy's list for Cassandra Clare's Mortal Instruments I loved those they rock.

Here are some of my favorite: I loved the Jemma Doyle Trilogy by Libba Bray its a great historical ya,Carrie Ryan's Forest of Hands and Teeth was pretty good too, Melissa Marr's Wicked Lovely series isn't bad either I've read them all and loved them, and last but not least Richie Tankersley Cusick's Unseen series is the bomb is not well heard of and older but it is right up there on the creep factor with Stephen King I loved them they left me wishing there were more. If your going to read the Unseen series I'd get the paperbacks here there are 4 books. I wouldn't get them in ebook they are expensive.

ETA: Unseen series is actually being rereleased in 2 volumes this year: and they have very few wishers

The Unseen Volume 1: It Begins/Rest In Peace :: Richie Tankersley Cusick

The Unseen Volume 2: Blood Brothers/Sin and Salvation :: Richie Tankersley Cusick

And if you’re going to read YA I suggest The Hunger Games even though they might not be paranormal they were great!

I'll add a DNR (do not read) if you don't want angst anything by Alyson Noel!

I can definitely recommend Vampire Academy and then the Bloodlines spinoff series (which I think I like even more). Also the Morganville series is very good too. Don't let the first book keep you from reading the rest of the series. While I liked it, the heroine was almost TSTL at times. She gets better though as the series continues. After the second book, I was hooked. It's got a lot of humor too.

I would second - Kelley Armstrong, Rachel Caine, Rachel Vincent, Rachelle Mead, Cassandra Clare, Kim Harrison, Melissa Marr, Libba Bray and Holly Black.

I would also recommend:

Lisa Mantchev

Garth Nix

Maggie Steifvater

Veronica Rossi

Laini Taylor

Kami Garcia

Lissa Price

Lauren DeStefano

Sarah Rees Brennan

Catherine Fisher

I've found a good way to check authors/books is to go into Amazon and read the reviews.  When you like an author you can always check the "Customers who bought this item also bought" - I've found some great authors that way.

Necromancing the Stone  & Hold Me Closer Necromancer by Lish McBride

Thanks for all the information guys.

I have a paperback version of Cassandra Claire's book coming.  (Are they making it into a movie?).

I have decided to try these four first whenever someone offers them on wishlist: 

Rachel Vincent: Soul Screamers

Kelley Armstrong

Richelle Mead: Vampire Academy 

Veronica Roth

I did end up with the first four Kristin Cast because of a really good deal; however, due to all the comments, I am not even sure if I want to crack open the pages.

Here are a few more suggestions:

Lili St. Crowe's Strange Angels series

J.J. Bonds' Crossroads Academy series

Maddy Edwards' Paranormal Public series

Yvonne Woon's Beautiful Dead series

Jana Oliver's Demon Trappers series

Andrea Cremer's Nightshade series

I am actually reading the vampire academy series and I love it. I just can't get my hands on book six.  I have also started Rachel Vincent's series and I like it so far and mortal instruments series

I love Tigers Quest, Iron Fey, Hex Hall, Trylle Novels, and soo many others. YA is amazing but can be very teenagey

Carrie Vaughn's     Jennifer Scales

Just have to put in a correction here, as I love my dragons.  The Jennifer Scales series was written by MaryJanice Davidson and her husband Anthony Alongi.

I love many of the YA books, too.  I will have to try out more on this list.  Of course I've read Sophie Jordan's Firelight series (more dragons), and would love to know about any other dragon series if there are any.

 "The Blue Girl" by Charles deLint was an enjoyable YA.
