Siren Says

“Mysterious, beautiful, and enchanting in the true and sinister sense of the word. You have been warned!” —Diana Gabaldon, #1 New York Times bestselling author of Outlander

A lush, spellbinding tale about a tenacious young woman who must harness her family’s dangerous magic to put a stop to the sacrifices they’ve been making for more than a century

Twenty-five-year-old Raven Wynn knows that the ancient plant magic running through her veins brings nothing but destruction. It doomed her Welsh ancestors. It killed her mother. It’s the reason she’s now bound by a painful curse—one that will destroy her if she can’t find a way to break its hold.

When her estranged Aunt Delilah bursts into her life promising a cure, Raven seizes the chance. However, her freedom comes at a steep price: Once her magic is fully unleashed, she is more powerful—and more dangerous—than anyone thought possible.

Desperate to tame powers she never wanted, Raven makes a pact with Delilah: In exchange for learning to control her magic, Raven will capture one of the spirits that roam Delilah’s hometown on May’s Eve so that it may grant Delilah’s secret wish. With the help of an enigmatic new friend, Cherry, as well as an infuriatingly handsome stoneworker, Idris, Raven learns that her task is even more perilous than she imagined—one false move and the spirits could trap her soul—forever.

A sumptuous escape into a world of Celtic spirits and botanical magic, Siren Says is a bewitching story of the unbreakable bonds between women, the interplay between goodness and power, and the capacity of love to mend our very souls.
