This audiobook is narrated by an AI Voice. In Anthracite, the floor is lava. Literally.

Built atop the Perpetual Fire, the mining city of Anthracite is a crumbling metropolis sinking inch by inch into a burning underworld. Ash falls like snow, the basements glow red, and survival depends on how well you can handle the heat.

Juno is a Heat-Mapper. Cold, logical, and numbed by trauma, she walks the scorching 'Crust' barefoot, using her senses to detect the temperature shifts that signal a deadly collapse. She is the city's early warning system, a woman who has turned herself into ice to survive the fire.

Dax is a Vent-Capper. A criminal serving a life sentence in the Deep Seams, he spends his days manually sealing the fissures where the inferno breaches the surface. Covered in burn scars and radiating a body heat so intense it blisters the air around him, he is volatile, dangerous, and untouchable.

When a catastrophic breach threatens the Aristocracy District, Juno is hired to guide Dax into the burning tunnels to seal it. But the descent into the fire reveals terrifying truths: the city isn't just burning coal, and Dax isn't just a prisoner.

Forced into a brutal partnership where the environment tries to cook them alive, the icy mapper and the burning convict discover a magnetic, ruinous attraction. He craves her coldness. She craves his fire.

But in a city built on an inferno, spark doesn't just ignite passion—it causes an explosion.
