When a teenage boy on a high-tech treasure hunt inadvertently stumbles into the middle of a crime, he finds himself in a dangerous situation that could turn deadly. After a summer cooped up in his family's store selling bait, tackle, and soft drinks to tourists, fourteen-year-old Chase finally gets a chance to go on his first solo geocaching adventure. Using his GPS, he uncovers the geocache--a small metal box--hidden deep in the woods in some undergrowth. Inside, with a few plastic army men and a log book, is a troubling message for help in a child's handwriting. When Chase returns later, he finds another message in the geocache box, this time asking for food. He is curious --and worried--about the mysterious individuals leaving the messages. What if they are hopelessly lost or hiding from something--or someone? Before he can turn to the adults around him for help, Chase is pulled into a complex, dangerous drama and a chilling confrontation with an unstable father who will stop at nothing to hold on to his children. Young readers will learn all about the high-tech adventure game of geocaching in Katy Grant's exciting novel that features heart-pounding action and surprising plot twists.
