Limitless Lands: Book 1: The Commander's Tale (A LitRPG Adventure)

Colonel James Raytak is about to die. The 93-year-old combat veteran is living his last days in a nursing home; his only hope for survival is an experimental Medpod life support system controlled by an Artificial Intelligence.
Co-developed by the world’s largest gaming company, Qualitranos the Artificial Intelligence will also control the soon to be released game Limitless Lands. Without its creator’s knowledge, the Artificial Intelligence decides the best course of treatment is to import its patient’s consciousness directly into the game.
Colonel Raytak must dust off his military training and lead his virtual troops in a fight to repair his broken body and mind while exploring the Limitless Lands.
