New York Times bestselling author Katherine Arden thrills once again in the finale to the critically acclaimed, spook-tacular quartet that began with Small Spaces.

It’s been three months since Ollie made a daring deal with the smiling man to save those she loved, and then vanished without a trace. The smiling man promised Coco, Brian and Phil, that they’d have a chance to save her, but as time goes by, they begin to worry that the smiling man has lied to them and Ollie is gone forever. But finally, a clue surfaces. A boy who went missing at a nearby traveling carnival appears at the town swimming hole, terrified and rambling. He tells anyone who'll listen about the mysterious man who took him. How the man agreed to let him go on one condition: that he deliver a message. Play if you dare
 
Game on! The smiling man has finally made his move. Now it’s Coco, Brian, and Phil’s turn to make theirs. And they know just where to start. The traveling carnival is coming to Evansburg.
 
Meanwhile, Ollie is trapped in the world behind the mist, learning the horrifying secrets of the smiling man's carnival, trying everything to help her friends find her. Brian, Coco and Phil will risk everything to rescue Ollie—but they all soon realize this game is much more dangerous than the ones before. This time the smiling man is playing for keeps.
 
The summer nights are short, and Ollie, Coco, Brian, and Phil have only until sunrise to beat him once and for all—or it’s game over for everyone.
Praise for Dark Waters:
An Amazon Best Book – August 2021

“Arden skillfully blends a creature feature with a survival tale, taking the series into new territory without deviating from its successful formula. The deliberate pacing maintains a palpable sense of dread, equally anxiety-inducing and terrifying. . . Another deliciously hair-raising entry in a series that continues to make a huge splash.” —Kirkus Reviews

“Describing the creepy setting where all the action takes place with cinematic detail, Arden piles on the terror, weaving in Lake Champlain history and pirate lore.” —Buffalo News

“The ending definitely ramped up the stakes once more and I’m now anxiously awaiting the conclusion to this dark, creepy middle-grade series. If you haven’t picked up this series yet, now is the perfect time to do so, if only to suffer with us all through the wait for the final book.” —The Nerd Daily

Genuinely spooky . . . Arden’s expert pacing and vivid descriptions ratchet up the tension deliciously, build eerie atmosphere, and make for some truly scary moments . . . [and] a tense cliff-hanger, which will leave readers on the hook for the next installment.” —Booklist

“Those who are attracted to mystery, adventure, and spooky stories will be drawn to this sequel like a moth to a flame.” —School Library Journal

“In this hair-raising novel . . . middle-grade readers, ages 8-12, and their adult reading companions, will be thrilled, and frightened, by this latest adventure. . . This is a very fun, and eerie, read-aloud.” —Addison County Independent

Praise for Dead Voices:

 “Arden handily transforms the haunted house story into something much richer, scarier, and more sinister. . . Middle-graders who thrill to spooks and scares will find plenty (maybe even more than they bargained for!) here.” —Bookliststarred review

 “Arden's high scare factor, richly drawn mountain setting, relevant themes of loss and belonging, and vividly eerie descriptions evoke the very best of horror for this age set.” —Kirkus Reviewsstarred review

 “In this spooky sequel to Small Spaces, Arden excels at creating an atmosphere of claustrophobic tension with memorably menacing details. Readers will again be invested in the ghoulish surprises in store for the resourceful, likably flawed protagonists.” —Publishers Weeklystarred review
