Magic is a rare gift, and it's been six months since Dominai of Airedale first left home to study it. After solidifying his place at the legendary Crux as a skilled conduit, he now faces his next challenge: casting. When every spell he attempts fails to hit the mark, he finally turns to the Grandmaster of the Crux, Arlon Kalisson, for guidance. The unyielding lessons that follow strip Dom down to his very foundation, rebuilding him to confront his own worst enemy: himself. But while Dom grows more confident inside the Crux, a threat gathers outside of it. One that will rock the kingdom of Straetham to its core, capable of destroying the Crux from the inside out. The second book of Alethea Faust’s epic Sex Wizards series, Mastery delivers risk-aware consensual kink, hard BDSM, an ever-escalating epic plot, and a lot of butt stuff.

The wizards of the Crux include pansexual, polyamorous, fantasy race, nonbinary, gender non-conforming and intersex characters. Please see book preview for full CW.
