It's 1968, and the Watry-Ridder family is feared and respected in equal measure. The local farmers seek out their water charms, and the teenagers, their love spells. The family's charms and spells, passed down through generations of witches descending from the Black Forest, have long served the small town of Friedrich, Minnesota.

Eldest daughter Elisabeth has just graduated high school—she is expected to hone her supernatural abilities to take over for her grandmother, the indomitable Magda. She's also expected to marry her high school sweetheart and live the rest of her life in Friedrich. But all she can ask is, why her? Why is her path set in stone, and what else might be out there for her?

She soon discovers that magic isn’t the only thing inherited in her family. That magic also comes with a great price—and a big family secret. The more she digs, the more questions she has, and the less she trusts the grandmother she thought she knew. Who is Elisabeth without her family? She must ultimately decide what she's willing to sacrifice for her family, for their secrets and their magic, or risk it all to pave her own way.
