The Witches of Cambridge is a historical fantasy set in 1950s Massachusetts, where first-year Radcliffe students Ava and Lauren are drawn into the secretive Lilith Society, a centuries-old coven of witches descended from women persecuted during colonial witch hunts. As their friendship deepens into something more, they uncover dark secrets linking their society to the past. With McCarthy-era paranoia rising and young witches mysteriously disappearing, they must confront the enduring legacy of fear, persecution, and prejudice before history repeats itself.
