Kirkus Reviews 'Howe's writing is suspenseful and effortlessly draws the reader in.' VOYA, starred review 'Engrossing and thought-provoking.' Boston Globe '[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 '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!' Christian Science Monitor '...this creepy, gripping novel is intimately real and layered, shedding light on the challenges teenage girls have faced throughout history.
