My first pick is a book that's not actually been published yet but I've already been drooling over the gorgeous cover :)
Ripple by Mandy Hubbard
Published July 2011 by Razorbill/Penguin
Lexi is cursed with a dark secret. The water calls to her, draws her in, forces her to sing her deadly song to unsuspecting victims. If she succumbs, she kills. If she doesn’t, the pain is unbearable. To keep herself and those she cares about safe, she shuts herself off, refusing to make friends or fall in love—again. Because the last time she fell in love with a boy, he ended up dead.
Then Lexi meets Cole. Against her better judgment, she finds herself opening up again, falling in love when she knows she shouldn’t. But when she’s offered the chance to finally live a normal life, she learns that the price she must pay to be free of her curse is giving him up.
In Ripple, Mandy Hubbard spins a sea-ravaged tale of melancholy beauty, and the choices one girl makes between land and waves, love and freedom, her future—and her heart.
