Soda Pop Soldier by Nick Cole is currently on sale for 1.99
Call of Duty meets Ready Player One in this fast-paced, action-packed novel from the author of The Wasteland Saga. Gamer PerfectQuestion fights for ColaCorp in WarWorld, an online Modern Warfare combat sport arena where mega-corporations field entire armies in the battle for real world global advertising-space dominance. Within the immense virtual battlefield, players and bots are high-tech grunts, using drop-ships and state-of-the-art weaponry to wipe each other out. But times are tough and the rent is due, and when players need extra dough, there's always the Black, an illegal open source tournament where the sick and twisted desires of the future are given free rein in the Wastehavens, a gothic dungeon fantasy world. All too soon, the real and virtual worlds collide when PerfectQuestion refuses to become the tool of a mad man intent on hacking the global economy for himself.
