From the back of the book:
Welcome to a world where your personal sidearm uses your body's mana as ammo and a vicious demon fuels the engine of your brand new ride. It's a world where spellslingers and mercenaries fight side-by-side against nightmarish monsters in the streets, while corporate cults are blinded by their pursuit of wealth and power. It's a world where every resource is pushed to its limit using arcane technology. When you die, not even your soul is safe. Mana fuels this ever-advancing society, and there is no richer source than the soul of a humanoid. This world is also one of opportunity and vicious beauty, it's a place of complex mysteries, unimaginable heists, exotic, dangerous locations, and death-defying battles. It's a place where risk-takers can truly thrive and where action hides behind every corner.
