New York Times bestselling author Katherine Arden returns with another creepy, spine-tingling adventure in this follow-up to the critically acclaimed Small Spaces and Dead Voices.Until next time. That was chilling promise made to Ollie, Coco and Brian after they outsmarted the smiling man at Mount Hemlock Resort. And as the trio knows, the smiling man always keeps his promises. So when the lights flicker on and off at Brian's family's inn and a boom sounds at the door, there's just one visitor it could be. Only, there's no one there, just a cryptic note left outside signed simply as-S.The smiling man loves his games and it seems a new one is under way. But first, the three friends will have to survive a group trip to Lake Champlain where it's said Vermont's very own Loch Ness monster lives. Brian is thrilled. He hasn't sailed since visiting his family in Jamaica and even the looming threat of the smiling man can't put a damper on what is guaranteed to finally be a day of fun-even if it is awkward being stuck on a boat with both his old best friend, Phil and his new best friends, Coco and Ollie. But when a misstep from Phil causes a tragedy onboard and leaves them shipwrecked on an island haunted by a monster on both land and sea, Brian's survival instincts kick in and it's up to him to help everyone work together and find a way to escape.One thing is for sure, the smiling man is back and he wants a rematch. And this time Brian is ready to play.
