Shot Through the Heart by Dominique Eastwick

Tegan Rees is a high-powered public defender. She fights for those who can’t fight for themselves. Her people have been around for eons, and as the moon moves into Libra, she is reminded yet again she remains without a viable mate.
Archer is an immortal bounty hunter or slayer sent to bring the shifters to ground. To his people, shifters no longer have a place in the world. With Libra rising, he must stop his hunt for Virgo and commence into Libra. Libras shifters have always been elusive as they hide behind the scales. But Archer is different. He and a handful of other Foniás only hunt the shifters who have done harm to humans.
Can both Archer and Tegan overcome prejudices long engrained in their people? Can Archer save his mate from his own people and hers when he discovers her hidden Raven?
