When Rowen Black is assigned to the elite unit of angelic assassins known as the Shadowguard, he thinks his biggest challenge will be overcoming his less-than-stellar reputation. But that's before he meets his match in Scarlet Montgomery.

Beautiful, strong, and with a temper to match Rowen's own, Scarlet is focused on the Shadowguard and her possible future as its leader. She's become an expert at keeping her personal life separate from the Guard, all too aware that as the boss's daughter, fellow warriors see her not as someone to be respected, but as someone to be protected.

Avoiding entanglements gets a lot harder when Rowen saunters into the room. Rowen puts the bad in "bad boy." Their connection is hot, visceral, and instantaneous.

When the pair is assigned to a joint investigation, they come face-to-face with their undeniable attraction, forcing Scarlet to consider that the connection is not only physical, but a destiny written in the halls of time.
