Empty Smiles / Katherine Arden.

It's been three months since Ollie made a deal with the smiling man to save her friends' lives and vanished without a trace. Coco, Brian, and Phil are beginning to worry if they'll ever see Ollie again when they find a mysterious note, possibly from Ollie, on a poster for a traveling carnival set to arrive in town. With their clue in hand, the friends attempt to track Ollie down at the carnival, but the sinister clowns running the show have alternate, horrifying plans and suddenly no one is safe.With only one way to get Ollie back and to save their town for good, Coco and Brian must play the smiling man's games one last time (this time on a creepy carnival midway), but they only have until sunrise-or game over. bokus.com
