Lynxar (Lynxar Series, Book 1) by Melissa F Hart
Scientist Dr. Rachel Deering hopes that her invention will lead her to find meteorites from outer space, but instead it leads her into an abandoned alley where trouble awaits. Fortunately, Rachel is rescued by a strange man with very surprising abilities. When he reveals to her that his name is Lynxar and that he is actually an alien from another world, Rachel vows to help him get back home. But can she do it before General Kriptoff finds them and uses Rachel’s research for his own evil purposes? Rachel certainly intends to try, but the one thing she didn’t count on was falling deeply in love with the handsome alien she was dedicated to sending home.
