The journey continues...
After discovering the horrific truth behind the Park Service, fifteen-year old Aubrey Van Houten has overthrown its leader with the help of his best friend, Jimmy, and his girlfriend, Hannah. But their victory has left all three parentless and alone in a world where drones still hunt humans. And while the Park Service founder might be dead, he's far from gone. Now, Aubrey's quest to free his people will lead him even farther into a world where nothing is what it seems.
Destined to become a classic, The Park Service trilogy will inspire and delight readers of all ages.
