Faye Kellerman and Aliza Kellerman. Prism. "Three teens. Disaster at midnight in an uncharted desert. And the next morning...a return to their ordinary lives with everything just as it was before. Or is it?"
Beth Kephart. Nothing But Ghosts. Loved her last book. This one looks to be just as promising.
Diana Peterfreund. Rampant. "Buffy the Vampire Slayer meets My Little Pony (gone very, very bad) in an exciting YA debut!"
