Not all of these were written in 2011, but whatever.
The Mercy Thompson Series by Patricia Briggs. I devoured em all.
A Kiss at Midnight by Eloisa James: 2nd best rendition of Cinderella EVER! Sorry, nothing can top the movie, EVER AFTER.
When Beauty Tamed The Beast by Eloisa James. The cool thing about that one is that I get a post card of the cover when she has a new release so for Valentine's day I give it to my husband and he takes it to the bookstore and says, "My wife wants this."
FATED and CLAIMED by Rebecca Zanetti: The first two in the Dark Protector's Series, Zanetti's vampires are HOT, Hot, Hot!
MUSTAINE by Dave Mustaine: Autobiography of the lead singer and guitarist of my favorite band, Megadeth. I usually don't care for autobiographies, but this one kept me turning the pages and had me alternating between laughter and tears.
THE HUNGER GAMES TRILOGY by Suzanne Collins: Yeah, I know I was late to the bus on this one, and damn, all the hype was well-deserved!
The WARRIORS series: by Erin Hunter: I usually don't read middle grade, but it was about cats, man! My son got me hooked on 'em!
STONE KISSED by Keri Stevens: Probably the most unique paranormal romance I read this year.
BREATHE AGAIN by Bonnie R. Paulson: A heart-wrenching tale of a woman's journey to love after suffering a tragic loss.
ONCE BITTEN and THE WICKED KISS by Trina M. Lee: The 1st two in the Alexa O'Brien Huntress series, Ms. Lee put the monster back in monsters.
HUNTED BY THE OTHERS by Jess Haines: The most fun urban fantasy that I've read in awhile.
MARKED and ENTWINED by Elisabeth Naughton: These were so engrossing I read MARKED while I was getting my 1st tattoo.
LORD AND LADY SPY by Shana Galen: It's like MR. AND MRS. SMITH set in the Regency...only waaaaay better!
SOUL REBORN by Jean Murray: I've now decided that Egyptian gods are hella-sexy!
11-22-63 by Stephen King: A high-school English teacher goes back in time to try to stop the Kennedy assassination. I can't believe how good this book was. I wanted to read it again as soon as I finished it.
