But everything changes when she is captured by a terrifying Kyrzon warrior who refuses to remove his helmet. Suddenly, she finds herself a prisoner to this big, stoic alien, bound to be sold to the highest bidder in a foreign land.
As they travel together, Selena begins to suspect that there is more to her mysterious captor than meets the eye. And despite his carefully calculated demeanor of stern authority, it seems that he might be harboring feelings for her.
When the masked alien decides to keep Selena for himself, the passionate romance that follows startles both human and Kyrzon alike.
