Atlantis is brilliant, powerful, and certain it cannot fall.

Young engineer Tayac has his future planned: earn his place at the School of Applied Technology, marry the woman he has loved since childhood, and build a life far from the politics threatening his homeland.

Then he drinks the wrong potion.

Bound by an irresistible desire to Adur, the guarded soldier assigned as his partner, Tayac tells himself their attraction is nothing more than magic. But as stolen moments become friendship, trust, and something far harder to name, the question becomes impossible to ignore: if the potion can create desire but not love, what is keeping them together?

Around them, Atlantis is beginning to fracture. The earth trembles, its miraculous technology strains, and whispers of the island's destruction are becoming harder to dismiss.

Caught between duty, betrayal and a love he refuses to recognise, Tayac may discover the truth only when there is no world left to return to.

A steamy, tragic queer romantasy inspired by Tristan and Iseult, set against the final days of Atlantis.
