Mary Frances Talbot—Frankie—is a necromancer, probably. Hard to say since she never met her parents. She can see the dead, talk to the dead, and a few other things that aren't strictly legal. It's fine. No worries. As long as she doesn't get caught. The whole not getting caught thing was going well until Samuel Harrow blew back into town wearing a Savannah Police Department uniform. He might be a witch, but he hates magic. He's not a fan of Frankie either. Which explains why he's her ex.

In the magical city of Coldstream, located on the border between Scotland and England, Kit is viewed as little more than mildly eccentric and mostly harmless.

All that changes, however, when a teenage werewolf shows up at her door in the desperate hope of renting out a nearby vacant flat.

To bring him to justice, she'll have to join forces with someone who wields an even more dangerous power.

After her ship takes damage, she's forced to re-route to a space station where her past and present collide with dangerous consequences. Kira's existence holds the key to a faltering peace treaty with the Tuann - a technologically advanced alien race who dislikes and distrusts all humans.
