County Mayo is rich in the traditions of Ireland, legends that Branna O'Dwyer fully embraces in her life and in her work as the proprietor of The Dark Witch shop. Branna's strength and selflessness hold together a close circle of friends and family. But there's a single missing link in the chain of her life: love. She had it once-just for a moment-with Finbar Burke, but a shared future is forbidden by history and blood. Which is why Fin has spent his life traveling the world to fill the abyss left in him by Branna, focusing on work rather than passion. Branna and Fin's relationship offers them both comfort and torment. A storm of shadows threatens everything that their circle holds dear. It will be Fin's power, loyalty, and heart that will make all the difference in an age-old battle between the bonds that hold their friends together and the evil that has haunted their families for centuries.
