Levi and Kat are about to discover a very dark side to their neighborhood. Nothing ever seems out of place in the safe, suburban town of Cowslip Grove. Lawns are neatly mowed, sidewalks are tidy, and the sounds of ice cream trucks fill the air. But now ... kids have been going missing--except no one even realizes it, because no one remembers them. Not their friends. Not their teachers. Not even their families. But Levi and Kat do remember, and suddenly only they can see why everyone is in terrible danger when the night air rolls in. Now it is up to Levi and Kat to fight it and save the missing kids before it swallows the town whole.
