Hector Briar may have walked away from the Witch Trials alive, but not whole.

His failure handed the Witch Hunters a weapon capable of shattering Witch-kind—and placed the ancient demon Bahmet firmly in their grasp. Now the Hunters are poised to burn magic out of the mortal world forever.

Arwyn Hopkin spent years living a lie. Meeting Hector changed that. Manipulation got him so far, until his success during The Witch Trials bound him to Bahmet, a demon who whispers promises, demands obedience, and hungers for freedom. Everyone wants to use Arwyn: the Witches, the Hunters, and the demon inside him. Surviving any of them may be impossible.

When Hector and Arwyn's paths converge, the Witch Trials ignite once more. Forced into a deadly contest of loyalty and power, Hector will do whatever it takes to stop fate from repeating itself. In Bahmet's domain, love becomes a weapon, trust a gamble, and every choice carries a cost that could reshape the world. Witches and Hunters face off in one final battle that will determine the fate of their world forever.

And beneath the rising chaos, desire sparks hotter than it ever has between them—dangerous, undeniable, and impossible to control. As enemies and lovers collide, their bond becomes both salvation and ruin, pushing them to the edge of temptation and betrayal. To claim each other—and save magic itself—sacrifices must be made, and the price of their passion may be the one thing neither is ready to give.

The Demon and His Viper is the final book in a MM paranormal romance series of heart-pounding romance, witchcraft, and bloodthirsty enemies, perfect for fans of The Serpent and the Wings of Night and Her Soul to Take.
