Smoke

Humans went underground to ‘save themselves’ for over twenty years after causing two Great Catastrophes that nearly ended the world. However, the preternatural entities have survived and thrived, except for suffering breeding issues that stunted the growth of Thunders, Packs, and Covens, among others. Without hope of finding their claimed mates, all could be lost.

Kai needs to save her sister. She is no stranger to loss. Even though she was around for the destruction of the world, she recalled the helpless pain of watching her parents die. Her sister is the only thing she has left, and if she must barter herself to the "God of Fire" to ensure her sister lives, she will.

Times are different now. Aodh's Thunder no longer expects him to take a mate, but he must choose someone to carry his offspring. The human who has wandered too far from safety may be his answer—or something more. He knows if he doesn't claim her soon, another on the shifter council will.

Note from the author: This book is part of a serial and should be listened to in order. Cliffhangers in books 1, 2, and 3, but ends with HEA in 4.
