Seanan McGuire’s New York Times-bestselling and Hugo Award-nominated InCryptid series continues with the fifteenth book following the Price family, cryptozoologists who study and protect the creatures living in secret all around us.

Children have always disappeared under the right conditions - slipping through the shadows under a bed or at the back of a wardrobe, tumbling down rabbit holes and into old wells, and emerging somewhere...else. But magical lands have little need for used-up miracle children. Nancy tumbled once, but now she's back. The things she's experienced...they change a person. The children under Miss West's care understand all too well. And each of them is seeking a way back to their own fantasy world.

Hundreds of years after the end of the world, the Appalachian community of Iron Hollow finds itself beset by demons. Such horrors are common these days in the outlands, where most folks die young—if they don’t turn into monsters first. When a legendary knight is summoned to hunt down the latest unearthly beast to haunt their woods, the town’s new oral historian, Shrike, has more reason than most to be concerned. Because that demon was her wife. And while Shrike is certain that May still recognizes her—that May is still herself, somewhere beneath it all—she can’t prove it.

In the small town of Thistleford, on the edge of Faerie, dwells the mysterious Hawthorn family. There, they tend and harvest the enchanted willows and honour an ancient compact to sing to them in thanks for their magic. None more devotedly than the family’s latest daughters, Esther and Ysabel, who cherish each other as much as they cherish the ancient trees. But when Esther rejects a forceful suitor in favor of a lover from the land of Faerie, not only the sisters’ bond but also their lives will be at risk…

Morgan Carter, owner of the Odds and Ends bookstore in Door County, Wisconsin, has a hobby. When she’s not tending the store, she’s hunting cryptids—creatures whose existence is rumored but never proven to be real. It’s a hobby that cost her parents their lives, but one she’ll never give up on.
