THE ALCHEMY OF RIVALS: A Dark Cozy MM Romantasy - The Thornveil Courts, Book 1

He distills grief. His rival bottles desire. Neither of them was supposed to need the other to survive.

Caelan Ashveil built his life on three the scarred workbench of The Black Vial, the golden circuit lines running wrist-to-elbow that mark him as something the Ash Court couldn't control, and the absolute certainty that he works alone. For five years, the shadow market has been his territory — a curated library of human misery, cataloged in cobalt-black vials and traded in coin and silence. He doesn't do charm. He doesn't do hope. He does the work no licensed alchemist will touch.

Then Soren Nighthollow sets up three stalls down.

All polished copper and court-minted legitimacy, the Mist Court alchemist arrives with dark auburn hair, three orbiting teal orbs of light, and a smile sharp enough to steal Caelan's contracts before the fog lifts. He sells joy. He sells desire. He sells everything Caelan has always called a lie in a pretty bottle. And he is, infuriatingly, brilliant.

When a shadowy client hands them both an identical, impossible commission — a compound that distills to a bruised violet-black and smells of nothing, of absence — they are forced to compare notes across the threshold of the shop Caelan never lets anyone inside. Neither can name what they've made. Neither can make it alone.

Then the client turns up dead in an alley. And two Court enforcers arrive with a name for what they've conspiracy.

Thirty days. Find the real killer. Expose the network that engineered their collision. Or face a joint execution order signed by the Chancellor himself.

Thirty days of working side by side at a scarred blackwood bench. Of cedar bleeding into cardamom until neither of them can tell where the other ends. Of watching Soren's careful, court-polished walls develop exactly the same cracks Caelan spent twelve years building his own around.

The world they're trying to save wants to execute them both. The magic they discover — when gold circuit lines braid through teal light and produce a color no alchemical lexicon has ever named — is not in any formula either of them was trained to make.

Caelan can distill every shade of grief in existence.

He never expected one of them to be the thought of losing this.
