Rise (A Titan's Core Book 1)

In this tower, death costs a year of your life. Joe can’t afford to die. Trapped in a deadly gauntlet of kaiju guardians, warring factions, and brutal system mechanics, he’ll need a hacker’s mind, volatile MadOrbz, and a talent for breaking the rules to survive. But in a game where time is currency, even immortality comes with an expiration date.
