Immortals do it forever.

Raven Strigoi has the perfect job. The daughter of Tobias, a powerful Lamai vampire, she's a natural fit as medical examiner for the magical island community of Mirabelle Cove. As the enclave of preternatural beings prepares for dark hibernation, Raven looks forward to spending more time with Bo, her destined mate. Instead of peace, autumn brings with it an undercurrent of evil.

Detective and Native American shapeshifter Bo Wasake can vouch for the fact Raven is no slouch in the brains and beauty category. He's loved her since the day they met. Now their happiness is threatened by a sorcerer known as Courtier de Sang. De Sang's viral vendetta can't touch Tobias, but targets what Tobias loves most—his family.

Raven fights desperately to keep the epidemic contained, but the recombinant virus has mutated and jumped species—to Bo.

And time is running out.
