Relentless — B.J. McCall

A Hellhound on the scent is relentless.

Hellhound Haydn North is hired by Ridax Pharmaceuticals to track down stolen vials of its new heart drug which has an unexpected side effect. Stolen by a lab tech, the aphrodisiac is now on the streets being sold under the name of Raptus.

Private procurer Kartinka Kruse is hired by a wealthy client to acquire the vials of Raptus only to find Haydn is on the case. This isn't the first time she and the Hellhound have crossed paths.

Haydn has been romancing Kartinka for months, and his relentless pursuit is wearing her down a kiss at a time, but alpha male Hellhounds like to lead, and Kartinka doesn't like to follow.

Haydn's hunt for his alpha mate is over. All he has to do is convince Kartinka she's his perfect mate.
