Mystery of the Eagle's Nest — Tamra Wight

Trouble has returned to Wilder Family Campground. When Cooper and Packrat find their geocache box full of illegal eagle parts, their lazy summer is over. Someone wants those valuable parts back. And if they can't get the parts back, they'll settle for holding one of the rare Pine Lake eaglets hostage instead. Cooper, Packrat, and Roy must elude two goons, tolerate an annoying teenager, keep tabs on a shady new camper, and stake out the eagle's nest -- all without getting grounded. Tamra Wight has written an exciting follow-up to Mystery on Pine Lake, a tale ripe with adventure and natural history, but above all, one of compassion and friendship.
