Khalani is a Prisoner. Takeshi is a Guard. Both are slaves to the Underground. Khalani Kanes has never stood on the surface of the earth. In the underground city of Apollo, faith and dreams are as absent as the sun. She longed to visit Genesis, the infamous Domed City and the final place where humanity lives aboveground. But when Khalani is given a life sentence and thrown into prison for a theft she didn't commit, those wishes shatter into oblivion. In Braderhelm Prison, murderers are neighbors, ruthless and cold-blooded guards live to punish, and every second is a battle to survive. She thought the danger lay in befriending criminals and avoiding Takeshi Steele, the nefarious Captain who runs her cell block. But darker traps and secrets await her within the shadows of imprisonment. Khalani's blood will coat the walls in flaming silk before her enemies let her escape to the surface, a feat no one has successfully achieved. If the reclusive and callous Takeshi Steele won't kill Khalani, then the merciless prisoners and her fractured mind will. Enter Braderhelm Prison, where only the Wicked remain.

Greta liked knowing people's secrets. That wasn't a problem. Until she met Big Swiss. Big Swiss. That's Greta's nickname for her - she is tall, and she is from Switzerland. Greta can see her dressed top to toe in white, that adorable gap between her two front teeth, her penetrating blue eyes. She's a including the heads of infants and dogs. Well that's how Greta imagines seeing her; they haven't actually ever met in person. Nor has Greta actually ever been to Switzerland. Greta and Big Swiss are not in the same room, or even the same building. Greta is miles away, sitting at a desk in her own house, wearing only headphones, fingerless gloves, a kimono, and legwarmers, transcribing this disembodied voice. What Greta doesn't know is that she's about to bump into Big Swiss in the local dog park. A new - and not entirely honest - relationship is going to be born. A relationship that will transform both of their lives.
