Finding Axiom Publisher's Summary
When Finn, a 16-year-old Enforcer-In-Training, learns that The Wall built to keep citizens safe from The Wild is really a cage, he starts questioning all he's been taught. Maybe animals aren't as dangerous as he's been conditioned to believe. Maybe his rebel parents aren't the bad guys. Maybe he's playing for the wrong team. Finn must choose a side; either way it will cost him. His family, or his future...but neither are as terrifying as what may lurk beyond The Wall.
