A View to a Kill — Mandy M. Roth

A trained assassin...a man even the deadliest of warriors fear. To cross him is foolish. To steal his heart is pure madness. Book two in King of Prey series.
Sachin, head advisor to the king of the Accipitridae realm, has been forced to put his trips to Earth on hold. He's not been honest with himself or King Kabril about his need to visit the primitive planet. The king thinks him to be a womanizer, out to bed as many human females as possible.
In truth, a woman he should have been able to woo with little to no effort-his mate-has found someone else to fill that void in her life. She wasn't supposed to be on Earth. She wasn't supposed to be human. And she sure the hell wasn't supposed to agree to marry another man while Sachin was away. Sachin must make a choice, give up the one woman he knows to be his true mate and let her live in ignorant bliss of what walks among her people, or fight for what's his, taking it at all costs. A trained assassin...a man even the deadliest of warriors fear. To cross him is foolish. To steal his heart is pure madness.
