A runaway spell is the most dangerous weapon of all.

Karin's watched magic ebb and flow over her long life. A healer by nature, as well as a wolf Shifter, she fixes what she can and buries her personal needs deep. In a race against time, she and a small group of Shifters and humans are sailing toward a gateway in the Arctic. If they can't close it, Earth will be doomed.

Daide's a scientist, first and foremost. Once a world-renowned expert on treating cetaceans, his skills are rusty. Ten years as a Vampire altered a whole lot, and he's still analyzing his brand-new Shifter magic. Karin caught his eye before they left Ushuaia, but she seems to be in love with a dolphin Shifter. Immersed in jealousy, Daide considers walking away, but he can't give up. The only woman he's ever loved is worth fighting for. Consequences be damned.

Vampires, Witches, high-handed gods, Kelpies, and a host of others all want either the ship or the Shifters' magic. Even the simplest tasks grow thorny edges, and misunderstandings threaten to destroy everything.
