Alexa (Married to the Aliens #1)

Alexa's family lost everything during the technology bust that left Earth dependant on the Xerrians. Her only remaining commodity -- a rare blood antigen that makes her capable of bearing an alien child.

If she wants to save her little sister Sofia from a life of poverty, Alexa has little choice but to enter the Alien Brides program. She's offered the chance to marry a pair of wealthy aliens, who agree to pay Sofia's way into a good school and a better future.

Alexa finds herself on a trip out-of-this-world and into the bed of two very alpha males. Will they recognize just how priceless her soul is, or will she be nothing more than a sex slave?
