After his parents' separation uproots him from everyone and everything he's ever known, Spencer tries to bury himself in video games. That's easier said than done when his game systems are miles away, and the only game shop in town doubles as a smoke den. Ready to give up, Spencer is introduced to Monster Gear—an augmented reality, geocaching, monster-taming RPG for his phone. Thinking it's just another mobile game, Spencer is ready to try it and toss it aside. There's only one problem: the monsters are real. With Zero, his new monster friend, and a guild of like-minded players, Spencer is ready to tackle any challenge the game has to offer!
