Kase Garrick faces his greatest challenge yet in the How to Set the World on Fire series, as he does everything in his power to keep his family, friends, and girlfriend safe.

After being promoted to High Guardian, Kase's mission is to hunt a group of fugitives across the realm. With his task force at his side, Kase will need to use both his wizard and warrior abilities to gain an advantage, track down the criminals, and capture them one by one.

Inspired by her boyfriend's success, Lenia convinces Kase to be her warrior professor. While the other Liberati's lives get busier—Talen balancing her professional work and personal research, and Cali with her new responsibilities at the Triple Crown—Kase and Lenia find time to focus on what is most important to them: each other.

But when an old enemy resurfaces, Kase gets trapped. Taught never to back down, never to surrender, and never to give into the demands of his adversary, Kase must forget what he has learned to make a foul decision: to help his enemy so he can save his friends.
