Can they uncover the truth before the killer strikes again, or will their trust unravel under the weight of buried secrets?

Fresh off her first successful case, Agent Harvest Rosenbloom is eager for a relaxing Christmas break at her family's enchanted home on a magical island off Florida's coast. But her plans for tranquility are shattered when she stumbles upon a dead body, clutching a business card from none other than her swoon-worthy colleague, Agent Julian Quinn.

Quinn is no ordinary agent; he's a centuries-old vampire with a complicated past and more skeletons in his closet than he would care to admit. Working for the Bureau—a secretive magical law enforcement agency—he's found a grim sort of redemption, even if it does little to quiet his inner demons. He's even looking forward to working on another case with Harvest.

But like most investigations, nothing is as straightforward as it seems: tension flares between them, suspects are scarce, and the arrival of someone from Harvest's past threatens to derail everything. With the stakes rising, the duo must untangle a web of secrets—both old and new—while confronting their own haunted pasts.
