It’s senior year at St. Joan’s Academy, and school is a pressure cooker. College applications, the battle for valedictorian, deciphering boys’ texts: Through it all, Colleen Rowley and her friends are expected to keep it together.

Until they can’t.

First it’s the school’s queen bee, Clara Rutherford, who suddenly falls into uncontrollable tics in the middle of class. Her mystery illness quickly spreads to her closest clique of friends, then more students and symptoms follow: seizures, hair loss, violent coughing fits. St. Joan’s buzzes with rumor; rumor blossoms into full-blown panic.

Soon the media descends on Danvers, Massachusetts, as everyone scrambles to find something, or someone, to blame. Pollution? Stress? Or are the girls faking? Only Colleen—who’s been reading The Crucible for extra credit—comes to realize what nobody else has: Danvers was once Salem Village, where another group of girls suffered from a similarly bizarre epidemic three centuries ago . . .

Inspired by true events—from seventeenth-century colonial life to the halls of a modern-day high school—Conversion casts a spell. With her signature wit and passion, New York Times bestselling author Katherine Howe delivers an exciting and suspenseful novel, a chilling mystery that raises the question, what’s really happening to the girls at St. Joan’s?

Praise for Katherine Howe's Conversion

"...this creepy, gripping novel is intimately real and layered, shedding light on the challenges teenage girls have faced throughout history. Particularly in situations of powerlessness, Conversion shows, stress can reveal itself in mysterious ways."
—The New York Times
"Conversion melds the best bits of private school drama (think Curtis Sittenfeld’s Prep) with the mystique of the supernatural. Pick it up this fall for a good old-fashioned mystery and maybe even a flashback to your high school years (for better or for worse). Be prepared to love this bewitching page-turner!"
—The Christian Science Monitor
"[Howe] has a gift for capturing the teenage mindset that nears the level of John Green....there's no one better to bewitch teens and adults alike with a modern tale of gripping panic."
—USA Today
"....thrilling....A chilling guessing game of a novel that will leave readers thinking about the power (and powerlessness) of young women in the past and present alike."
—Publishers Weekly, Starred Review
"Engrossing and thought-provoking"
—Boston Globe
"How is it possible for a novel to be funny, suspenseful, tender, wickedly satiric, and terrifying all at once? When it's written by the bewitchingly talented Katherine Howe. Once again she transports us back in time to the tragic events in Salem Village that led to the deaths of more than twenty innocent citizens. This time, however, she turns an equally discerning eye on the academic and social pressures of an elite private school in contemporary times. The parallels she draws between the two worlds are provocative and haunting; whether you're a parent or a high-school student, you'll never look at the college rat race the same way again!"
—Julia Glass, National Book Award–winning author
