HIDDEN AWAY ...The Craze of Geocaching! — Phyllis J. Perry

In this novel,thirteen-year-old Troy Thompson has moved from
Texas to Boulder, Colorado, a month before he is to begin eighth
grade. Because he knows no one in town, he turns to his old
hobbies of geocaching and skateboarding to fill his summer time.
While hunting caches and practicing skateboarding tricks,
Troy makes friends with Lisa Jo and her grandfather and makes
enemies of three boys entering ninth grade. When part of
Lisa Jo's inheritance is hidden away in a cache, geocaching
becomes more than a game.

Geocaching is an outdoor recreational activity in which the participants use a Global Positioning System (GPS) receiver or other mobile device and other navigational techniques to hide and seek containers, called geocaches or caches, anywhere in the world.
A typical cache is a small waterproof container containing a logbook where the geocacher enters the date found and signs it with established code name. Plastic storage containers may hold items for trading, usually toys or trinkets of little value.
Geocaches are currently placed in over two hundred countries around the world and on all seven continents, including Antarctica, and the International Space Station.
After more than twelve years of activity, there are nearly two million active geocaches published on various online sites. Some estimates suggest there are more than five million geocachers worldwide.

HIDDEN AWAY, a story about geocaching, and skateboarding, is intended for all enthusiasts and the young at heart, but particularly those aged 10-14.
