It's Halloween night when strangers come to Linden Street . . . and something absolutely vital to Olive goes missing. To what lengths will she go to get it back? Can she trust the strangers? Will she turn to a new and dangerous magic within the paintings of Elsewhere? Or will Olive put her faith in her own worst enemies to save the people and home she loves?
