Leopard’s Kiss (Shadow Guardians #1) by Stephanie Rowe

In New York Times bestselling author Stephanie Rowe’s new shifter series, an ice-cold billionaire assassin must save the woman he was assigned to kill.

Driven by the need to avenge his family’s murder, billionaire Slade Cross has become a deadly assassin who kills with his kiss. He lives in the shadows and trusts no one…until a hit gone wrong thrusts him directly into a role he can’t afford: to protect instead of kill.

Desperate for help saving her kidnapped sister, Anya Diaz refuses to allow her personal assassin-turned-guardian to retreat behind his cold mask. Her irreverent determination drags Slade out of his self-imposed isolation, forcing him to engage.

Raw, explosive passion ignites between the two guarded souls as they race to save those they love, but a brilliant and ruthless enemy is closing fast, determined to finish what he began so long ago.
