The Shifter’s Salvation by R. A. Boyd

Audra Defoe’s slow descent into madness has finally reached the breaking point, but that doesn’t stop her from hoping that her mate will come and return her sanity. Her grace. It’s her only hope. If her happily ever after doesn’t show, she’ll be put under for the next century.
Zeke Santos has been warned to stay clear of the Ghost Shifters. Collect his ward, and get back to the Coven of the Fallen. In and out. Simple as that. All he wants is to do his job, but now the beautiful and insane Audra has roused a part of him he swore to never let free.
Can Zeke put her down before he’s completely under her spell, or will Audra’s beast force him to face a truth that he’s been running from since his fall from grace.
