Dying Wish — Shannon K. Butcher

Jackie Patton has been rescued by the Theronai from her captivity and torture at the hands of the Synestryn, only to learn that she's a potential match for the Theronai warriors who need a woman to literally save their lives.

Forced to choose, she unexpectedly selects Iain, a cold-hearted warrior who doesn't want to be saved. Iain is convinced that it's too late-that his soul is already as dead as his former betrothed, killed by the Synestryn. Still, he is the only one she wants. But is Iain indeed beyond saving?
