Tower (Tower #2)

Casandra, Kimi, and Mac were thrust into a brutal (and seemingly virtual) world where they must compete in a dangerous video game-style competition, and now it's time to level up! The trio has formed an alliance as they work their way up the Tower, but they're not the only ones with this idea; TEAM R.A.D. is off to a hot start, climbing to the top of the leaderboard. And if that's not bad enough, a rogue presence has entered the game and is hunting down contestants one-by-one.
