The Brigade enters people's memories to help them remember and look ahead. But when a classmate, Sofiane, is kidnapped--and doesn't remember what happened!--it's up to the Brigade to crack the case. Plus: Alice is developing problems with her own memories! And when a new woman arrives at the clinic, with memories of a town afraid of the night, can the Brigade survive and help everyone?"--Back cover.
