She's a 300-year-old Fae assassin with a bloodstained soul.

He's the mortal High King's chief enforcer, responsible for hunting and killing her people. Their marriage will be the breaking—and the making—of them both.

Bree Fellshadow is a master assassin, but when she's sent to work as a spy in the enemy court, she finds herself out of her depth.

Killing the queen's enemies is easy compared to pretending to be a biddable wife or dealing with her obnoxious chief-enforcer husband—a powerful warrior-druid who both enrages and unsettles her.

Cailean mac Brochan is also worryingly suspicious, and she keeps drawing his attention. But Bree must gain his trust, to learn where and when the enemy will strike.

That is… if she survives long enough.

Outlander meets The Witcher and Throne of Glass. From bestselling author Jayne Castel comes a brand new, romantic fantasy duology, where druids, mortals, and Fae collide with Celtic myth. If you love stories about betrayal, sacrifice, divided loyalties, and redemption—and if you like fierce, stabby heroines, and grumpy, protective heroes—you won't be able to stop listening to this addictive romantasy.

This is book one in a duology and will end on a cliffhanger. Contains mature content. A complete list of content warnings can be found on the author's website.
