Joker - Z Boys

It's only a game while you're smiling. Scotty Evans used to be the perfect soldier. An intelligence officer for the RAF, his loyalty to rank holds until he discovers the worst betrayals come from within, dissolving as he falls into the void of addiction and grief. Bonded together in the Z Unit brotherhood, an Australian military venture that doesn't officially exist, Scotty wears his designated call sign as a mantle, warding off anyone who comes too close to digging into the ruined soul beneath it.
To complete his mission he has to return to Trilogy, the gambling den where he left his innocence and dignity to uncover an illegal arms deal. But he's not the only one with a mission.Analise Larsen has lost something, too. Searching for her wayward sister, her objective throws her into Joker's path in a clash of wills, snark and dark desire. Escaping the casino unscathed seems impossible, if they can leave at all.
