Desire’s Destiny by Bethany Drake

Heather can’t believe she is the only person on Earth who can protect Storm, the ambassador from Vespia. It has something to do with some pheromone the Vespian males exude. Although everyone says she’s immune, she doesn’t agree. There is something about the man that makes her desire skyrocket whenever she is around him.
Storm finds Heather fascinating; her bright violet eyes hold a world of emotions in them. He’s drawn to her and wants her with a depth he’s never experienced before.
When she becomes the focal point of several kidnapping attempts, he realizes she’s going to need his protection: the perfect excuse to get to know her better.
