Baltimore homicide detective Malcolm Khalaji has his own way of doing things: quiet, methodical, logical, effective, not always particularly legal. He’s used to working alone—and the last thing he needs is a new partner ten years his junior.

Especially one like Seong-Jae Yoon.

Icy. Willful. Detached. Stubborn. Seong-Jae is all that and more, impossible to work with and headstrong enough to get them both killed…if they don’t kill each other first. Foxlike and sullen, Seong-Jae’s disdainful beauty conceals a smoldering and ferocious temper, and as he and Malcolm clash the sparks between them build until neither can tell the difference between loathing and desire.

But as bodies pile up at their feet a string of strange, seemingly unrelated murders takes a bizarre turn, leading them deeper and deeper into Baltimore’s criminal underworld. Every death carries a dangerous message, another in a trail of breadcrumbs that can only end in blood.

Malcolm and Seong-Jae must combine their wits against an unseen killer and trace the unsettling murders to their source. Together, they’ll descend the darkest pathways of a twisted mind—and discover just how deep the rabbit hole goes. And if they can’t learn to trust each other?

Neither will make it out alive.
