Dark Ties — Sarah Hall

Asire Thomas has spent the last five years living in the City of Orphans, with the threat of death looming over her. Now, she has the chance to escape. Loki Heron has gotten her a furlough to Arizona, to attempt reversing her orphaning papers. Asire's family is reluctant to comply, but he's determined to free her. After one mind turning kiss, Loki decided that there was no moving on from his dead mate. Even for Asire. To be with her would be crossing a line, and betraying his late mate. Though everything about Asire tempts him. Her strength, her beauty, the fire in her eyes. To make matters worse, spell-casters are drowning all over Arizona. Asire's brother asks her for help when his boyfriend goes missing. She and the Heron Family have to figure out who is causing the deaths, before all the spell-casters are wiped out.
