WHAT ROUGH BEAST
by Mindy McGinnis
HarperCollins, October 2026
In a small town like Bethington, nothing stays buried forever…
Ava Germaine has learned her lesson: see something, don’t say something. Cast out at school, the only place she can find peace is Restoration Acres, the town’s animal sanctuary. Though the place sometimes seems more like an animal graveyard than a rehabilitation center, Ava’s job there is at least a constant distraction from the night everything went wrong—and the boy she still holds responsible.
Micah Harding is always prepared for the worst. As the sheriff’s son, he tries not to do things that reflect poorly on his family, especially since his dad helped him cover up his worst mistake yet. But he knows his secret is bound to come out.
Hailey Wagner is sick of being judged. And finally, things are going according to plan—until Ava Germaine starts talking. So if Hailey has to shut her up…she will.
As a strange entity begins to stir, ready to awaken—Ava, Micah, and Hailey find themselves wrapped in a centuries-old exchange, while barreling towards the truth of what ties their fates together.

Fallon is a fixer. From planning prom to organizing her college applications, she’s got it all figured out…except for when her younger sister comes to her with very basic questions about sex. Shocked that she knows so little—and her fellow classmates even less—Fallon decides some practical education is in order. And Fallon isn’t above practicing a little civil disobedience by creating a secret underground off-campus group.
Lydia Chass doesn’t mind living in a small town; she just doesn’t want to die in one. A lifetime of hard work has put her on track to attend a prestigious journalism program and leave Henley behind until a school error leaves her a credit short of graduating. Undeterred, Lydia has a plan to earn that credit: transform her listener friendly local history podcast into a hard hitting, truth telling expose. She’ll investigate the Long Stretch of Bad Days a week when Henley was hit by a tornado, a flash food, as well as its first and only murder, which remains unsolved. But Lydia needs help to bring grit to the show. Bristal Jamison has a bad reputation and a foul mouth, but she also needs a credit to graduate. The unexpected partnership brings together the Chass family name a pillar in the community and the rough and tumble Jamison’s, of whom Bristal hopes to be the first to graduate. Together, they dig into the town’s worst week, determined to solve the murder. Their investigation unearths buried secrets;a hidden brothel, lost family treasure, and a teen girl that disappeared. But the past is never far, and some don’t want it to see the light. As threats escalate, the girls have to uncover the truth before the dark history of Henley catches up with them.
