Caged Warrior — Lindsey Piper

The first installment in this fierce and sensual new paranormal romance series features demonic gladiators, ruthless mafia villains, and a proud race on the brink of extinction.

Ten years ago, Audrey MacLaren chose to marry her human lover, making her an exile from the Dragon Kings, an ancient race of demons once worshiped as earthly gods. Audrey and her husband managed to conceive, and their son is the first natural-born Dragon King in a generation--which makes him irresistible to the sadistic scientist whose mafia-funded technology allows demon procreation. In the year since her husband was murdered, Audrey and her little boy have endured hideous experiments.

Shackled with a collar and bound for life, Leto Garnis is a Cage warrior. Only through combat can Dragon Kings earn the privilege of conceiving children. Leto uses his superhuman speed and reflexes to secure the right for his two sisters to start families. After torture reveals Audrey's astonishing pyrokenesis, she is sent to fight in the Cages. If she survives a year, she will be reunited with her son. Leto is charged with her training. Initially, he has no sympathy for her plight. But if natural conception is possible, what has he been fighting for? As enemies, sparring partners, lovers, and eventual allies, Leto and Audrey learn that in a violent underground world, love is the only prize worth winning.
