John Ridley's Those Who Walk In Darkness is a futuristic, sci-fi thriller filled with superheroes and super cops in a battle between good and evil. Soledad O'Roark is a tough, no-nonsense rookie on an elite team of police officers whose sole mission is to capture and deport metanormals. Metanormals are humans who have altered genetic traits which enable them to perform extraordinary feats, like fly, manipulate elements (metal, fire, water), become intangible (move through solid objects), etc. However, the most feared and deadly of the metanormals is the telepath who can enter the mind and take total control of one's actions, emotions, and thoughts with little to no warning. If you are picking up a strong "X-Men" vibe, then you are right on point.

LAPD'S top mutant-hunter, Soledad O'Roark has outfought telepaths, human flamethrowers, men with steel skin, and every other kind of freakish super-powered thing. But her high-tech firepower is no match for teammate—and rival—Eddi Aoki's attempts at friendship, which endlessly solitary Soledad. When a vigilante starts killing metanormals without mercy, Soledad and Eddi eend up working the same case... in a way that neither could imagine. And the hunt for answers pits Soledad and Eddi against a cabal inside the LAPD as well as a serial killer who's slaughtering mutants, cops, and anyone else who gets in his way.
