For a year or so, I've been reading a few Newbery-winning books (here and there) for my Newbery Project. I don't ordinarily read children's books since I don't have kids and I've got more books in the "to read"/"READ THIS NOW" pile than I can deal with some days. This extends to teen and YA books - no time unless it's for a specific reason (like when my little bookclub read Speak by Laurie Halse Anderson). I read Twilight and it's spawn because of my friend Jackie (who loves them) and to actually be able to legitimately state my opinion on whether or not the series is "good". I don't really "browse" the teen section at the store in the same way I "browse" regular fiction - I browse fiction to find things to read, I browse Teen so I can find the books later when needed.
However, there are a number of really intriguing books for teens/young adults on the market or in the works. The Hunger Games series, Dormia, the Uglies series, Wintergirls, The Maze Runner, ttyl/ttfn/l8r,g8r, Stargirl, Sold, etc. They all look to have good stories and I like good stories (and sometimes I need a break from my Victorians/Edwardians). I get some information on YA books peripherally through being a bookseller but there are a couple of bloggers who really have a focus on YA and give credible reviews.
Kristi at The Story Siren: Kristi reviews YA books of nearly every stripe and color. She is always fair in her reviews so I know that I'm getting a good opinion when I read a post on her blog. She's also very up-front about blogging issues/questions and happy to help out a newbie.
Pam at Bookalicio.us: Pam is a passionate reviewer of books. She has such a unique voice (and is wickedly funny - have you seen her "HP got hosed at the MTV Movie Awards" video?) Pam also recently hosted a series of guest posts speaking out against censorship. I always look forward to seeing Pam's posts pop-up in my Google Reader.
Pam and Kristi (and many more bloggers) have inspired me to read more YA. This is a new thing (starting with Lauren Myracle's Internet Girls series, read for my store bookclub reading topic "language" this month) and I'll be building my reading list as I go. I also find reading more YA important as September moves toward Banned Books Week (starting September 25). Children's and teen/YA books are very often the target for censorship because of subject matter but the reality is that reality is worse than fiction in 99.99% of instances.
