A year ago Sophie Wickham stumbled into the isolated Lancashire village of Withered Hill, naked, alone and with no memory of who she is. Surrounded by a thick ring of woodland, its inhabitants seem to be of another world, drenched in pagan, folklorish traditions. As Sophie struggles to regain the memories of her life from before, she quickly realises she is a prisoner after multiple failed escape attempts. But is it the locals who keep her trapped, with smiles on their faces, or something else, lurking in the woods?

Connie can't deny she's nervous about meeting her boyfriend's family. Spending the weekend at their ritzy woodland summer home, Evan's already given her fair warning that his parents are cold, snobbish, and especially unpleasant toward those outside their usual social circles. So when Evan's mother warmly greets them with open arms, Connie is as confused as he is. They're so friendly, in fact, Evan himself can hardly believe they're real. Then, while helping Evan's mother with dinner, Connie overhears strange noises coming from the basement—what almost sounds like voices calling out for help.

Since time immemorial, the Haddesley family has tended the cranberry bog. In exchange, the bog sustains them. The staunch seasons of their lives are governed by a strict covenant that is renewed each generation with the ritual sacrifice of their patriarch, and in return, the bog produces a “bog-wife.” Brought to life from vegetation, this woman is meant to carry on the family line. But when the bog fails—or refuses—to honor the bargain, the Haddesleys, a group of discordant siblings still grieving the mother who mysteriously disappeared years earlier, face an unknown future.

You may think you know how the fairytale goes: a mermaid comes to shore and weds the prince. But what the fables forget is that mermaids have teeth. And now, her daughters have devoured the kingdom and burned it to ashes. On the run, the mermaid is joined by a mysterious plague doctor with a darkness of their own. Deep in the eerie, snow-crusted forest, the pair stumble upon a village of ageless children who thirst for blood, and the three “saints” who control them. The mermaid and her doctor must embrace the cruelest parts of their true nature if they hope to survive.
