Her Battle Lord's Desire. The Battle Lord Saga, #2

Besieged by Bloods and placed on a hunger watch, the citizens of the mutant compound of Wallis turn to the one person they pray will help, the Battle Lord of Alta Novis.  Despite the fact that they took away the woman the man risked his life to love, they hope he will show mercy and lend aid.  They never expected to find Atrilan Ferran alive and thriving as the wife of Yulen D'Jacques.  Yulen sees this as the perfect opportunity to show the citizens of Atty's home compound the power and status his wife wields.  But first he, Atty, and his soldiers have to risk the journey against the oncoming horde of blood-thirsty crazies to get there.
Atty is eager to return to Wallis, but one small detail stands in the way of her and Yulen's happiness.  He desires an heir, and she is terrified at the thought of becoming pregnant.  Worse, the dangerous trek has increased his ardor, and she is running out of excuses why they can't make love.
