Best lesbian fiction of the past decade?

I am looking for young adult lesbian fiction. I haven’t read any yet, but am going to the bookstore tomorrow. I’m thinking about getting:
Same Sex in the City- Lauren Levin, Lauren Blitzer, Keeping You A Secret- Julie Anne Peters, 12. Love, Ellen: A Mother/Daughter Journey- Betty Degeneres, and The L Word Book-Jennifer Beals.

I am specifically looking for coming-out stories, and characters who are fairly young (teens, 20’s, and 30’s) if you can make any recommendations. If not, feel free to share what you have enjoyed. Oh and a small, short summary would be nice.
