Kiss of the Blood Prince

When the gateways at Stonehenge tear open on the winter solstice, and a horned fae prince walks out of them with an army, Elise Carlisle's commute home becomes the worst thing she has ever survived. He kills every passenger in her train carriage with a single golden wave of magic and finds, to his own fury, he can't destroy her too.

Kian, the Blood Prince, has spent centuries planning revenge on the human kings who betrayed his people and has returned to Albion to end their bloodlines. Instead, he's stuck with a fragile captive he's supposed to despise, a court full of fae who would happily gut her on sight, and the slow, infuriating certainty that the gods have chosen this infernal woman as his mate.

The longer Elise remains with Kian, the more she learns about the betrayal at the heart of his curse and the rot working its way through the three fae princes. He sets her to work restoring his ruined library, where the books bite, sing, and scheme. The monster who took her is harder to hate than she expected, and the bond singing under her skin is making it impossible to want to leave him.

Breaking the curse means giving Kian her blood willingly, and trusting him not to drain her dry.

If she fails, the curse takes him, and England will fall with him.

If she succeeds, she will never belong to anyone else again.

Either way, the fae are about to learn what a grieving, mouthy human with nothing left to lose can do.
