"Champion ""Phantom"" Jax did five years for manslaughter. Now she's a street punching bag, with only her girlfriend Mia still by her side. When her coach is held at gunpoint, Jax is forced back into the underground circuit—a betting puppet winning fights that only tighten the noose. Then Mia takes the bullet meant for her and falls into a coma. That coma was the last straw. Jax burns her bridges and steps into the ultimate cage. Tank Voss, the underground king, thinks he's hunting a broken fighter. He's wrong. He's hunting a phantom. And phantoms don't bleed."
