The Forgetting

In a society that loses its collective memory, one girl remembers everything! Every twelve years, the people of Canaan undergo a collective Forgetting, in the days before which the town devolves into a chaos of bloody violence, and after which the people are left without any trace of memory of themselves, their families, or their lives. Nadia has never forgotten, however. As the next Forgetting approaches, Nadia is determined to find out what causes it and whether there is any way to stop it.
