Cupid — M.L. Guida

Cupid, has a terrible secret -- she's color blind. After accidentally shooting her intended target with an aversion arrow, she tries to fix it by a shooting a passion arrow. But Lethal, the sexy angel of death she has had a crush on forever, blocks her path. Shot by passion's arrow, he now thinks he's in love with her.
Lethal knew Cupid was his angel-mate from the moment he saw her. He's never claimed her because an angry demon promised murder. But when she shoots him with the arrow he can't keep his true feelings hidden any longer.
The demon makes good on promise and pursues Cupid, but not to kill her. She has a hidden power he wants, one that Cupid doesn't even know she has. Only true love can unleash her power and by working together, their love will crush the demon bent on destroying them.
