amnesia

After being hit by a car, thirteen-year-old English girl Kat Tyler wakes up in the hospital with no memory of her previous life and must reconcile her new personality with her old when she reads the shocking secrets in her diary.

Jacob, having awakened in an empty field remembering nothing but his name, is taken to the nearby town of Locus where everything is gray--the clothes, the food, and the landscape--but he meets others who retain a spark of life, and enlists them in a quest to find the fabled Palace of Remembrance.

When a blow on the head gives Alfie the alligator amnesia, he thinks he's a human and scares many people as he tries to get near them.
