When the Morningstar fell, it wasn't holy light that defeated him-it was a perfectly executed Kimura lock.
Lucifer, once the most beautiful angel in creation, has spent millennia nursing a grudge and a terrible anterior pelvic tilt. Now the rematch against Archangel Michael is coming, and this time he refuses to lose on poor mechanics.
Enter Jax Miller: a burned-out personal trainer with zero patience for ego, terrible form, or apocalyptic nonsense. When a mysterious client offers him a ridiculous sum of money to transform a difficult individual, Jax expects a wealthy eccentric.
He doesn't expect the actual Devil.
What follows is the most unhinged training camp in history. Tungsten logs, melting equipment, jealous demonic tantrums, exploding restaurants, and one very awkward date interrupted by the Prince of Darkness. As the Genesis Rematch approaches, Jax must turn the Lord of Hell into a functional athlete before Michael finishes what he started in the Silver City.
Because this time, the War in Heaven will be decided by leverage, hip hinges, and who can actually tuck their wings under pressure.
A hilarious love letter to gym culture, biblical lore, and the eternal struggle of fixing terrible posture, Infernal Gains is perfect for fans of Good Omens, The Dresden Files, and anyone who's ever screamed at a client to brace their core.
Mass. Power. Gains. The Apocalypse has never been this jacked.
