Lusting the Enemy - Nightmix, #1

Akeisha is on a mission to be chosen as part of a harem for the desert king, Judas. She'll use her body to entice and beguile, do anything it takes to save the near-extinct larakytes, her shape shifting silver panther tribe, from Judas' human subjects, who are trying to eradicate them. She never expects to succumb to the wild ecstasy in his arms, a pleasure that threatens to expose her inner cat even as it transcends anything she's ever felt from one of her own kind.
Falling in love with a human enemy was never part of the plan, but maybe there's more to Judas than meets the eye
