In the wake of Pearl Harbor, SPOOK intelligence has discovered that the pilots involved in the attack were given a drug called Nirvana. A drug created by harnessing the powers of gifted humans. Having fought in dozens of wars on hundreds of battlefields, Sean McPhail - a squad leader for the Royal Air Force - is called into action to unearth the truth.
As Sean is forced to shed his human guise and accept his destiny, Jayne Foster continues to feel helplessly responsible for her father's death. Desperate to protect her loved ones, Jayne fell off the grid… but apparently not far enough. Clarke, a faction within SPOOK, has discovered she exists. Using her father's cold case as leverage, Eric Miller, a Clarke agent, convinces Jayne to join him as they look into her father's murder.
While Jayne tumbles down a rabbit hole of peculiar beings, murderous apparitions, and prophetic trains, Liam Reed, an assassin for The Book Club, must face a different world. Believing so blindly in the club's ideals, Liam followed every order without question, without hesitation, and without remorse. Until he was given an order he couldn't follow…
The morals he believed in for so long were shattered under a twisted mass of deceit, forcing Liam to turn against the only family he's ever known. In an act of defiance, Liam must choose to save another life over his own.
The Book Club, however, has other plans – for all of them.
Deep down in the depths of Fort Carroll lies one of SPOOKS most treacherous prisons, housing some of the most dangerous criminals in the multiverse. After years of planning and preparation, the Club has threatened to enact Protocol Thirteen, which will release hundreds of convicts upon the world, unless Jayne and her new friends can stop it.
