"My name is Jake. That's my first name, obviously. I can't tell you my last name. It would be too dangerous. The Controllers are everywhere. Everywhere. And if they knew my full name, they could find me and my friends, and then . . . well, let's just say I don't want them to find me."
Recently I re-read Animorphs, a book series I loved from my childhood about a group of kids who gain the power to morph into any animal they touch, and who are tasked to covertly defend Earth from an alien invasion.
Much like the Animorphs, geocaches are hidden in plain sight. Unlike the Animorphs, there's no time limit to find this cache! Be sneaky, Human-Controllers could be anywhere!
