my son needs some new books to read, but not sure what he wants to read....and i'm not sure what to recommend.  he has liked the a-z mysteries (but he is starting to outgrow them), also likes the goosebumps series.  he wasn't very interested in my other son's 'warrior' series.  i think he would probably enjoy those if he actually read them, but he has a 'thing' about animals being the main characters of the book.  anyway, i can't wait to see what other people have to recommend for us.  thanks!!

Jon Sczieska has a website devoted to getting books that boys are interested in.  Suggestions by age.  And a short story / essay collection.  The website is currently being updated.  But the book is on PBS.

There is also the author of the sports series.  Matt Christopher.

39 Clues and Diary of a Wimpy Kid, are extremely popular with my son and his friends.

Diary of a Wimpy Kid are one of my sons favorite and he's 10.  He also likes Captain Underpants (which I find totally ridiculous LOL), and he likes the author Andy Griffiths.

Hank Zipzer is huge with both my DD and DS.  My 10 year old DD loves Margaret Peterson Haddix's 2 latest series as well.  This is probably her favorite author right now.  They are science fiction and not girly at all.

My son loved the Animorphs by K.A. Applegate. Kids are given the abilty to "morph" into animals by an alien in order to fight an alien invasion. When they become the animals the books descirbe who they have to deal with the animals instincts.

Brandy,
I might be really old-school, but if your son enjoyed A-Z mysteries, perhaps he would like the Hardy Boys? There's also an older series of books about a child sleuth called Encyclopedia Brown.

Hope these help!

What about Artemis Fowl by Eion Colfer or the Ranger's Apprentice by can't think of the author  both good action series. He might also enjoy the DragonSlayers academy.

Rick Riordan's Percy Jackson series (The Lightning Thief is the first book) is a great read for boys that age.  My son loved them!

My son (now 12) doesn't love to read but he enjoyed the Alex Rider series about a child spy.  The first book is Stormbreaker (I have a brand new duplicate copy on my bookshelf right now, if you're interested).  He also liked Diary of a Wimpy Kid (a quick, easy read) and just asked for The Hunger Games, which many of his classmates are reading.
