Conversion, by Katherine Howe, is based on the very real case of the twitching girls in Le Roy, New York. Tensions are high between a group of second-semester seniors at an elite private school in small-town Massachusetts, vying for spots at the same Ivy League colleges. Howe draws parallels between the mysterious illness that befalls her protagonists and the Salem Witch Trials of the late 17th century, in which a group of tween girls faked an illness and pointed their fingers, leading to the deaths of 19 adults, most of them women.Read about the other books Fitzpatrick tagged.
