Sammy Keyes and the Wild Things

This is not the summer camping trip of Sammy's dreams. She imagined shady glades, meandering streams, a deer or two. What she gets are scrubby shrubs, blazing sun, rattlesnakes, ticks, and scorpions. Her fellow campers are desperate to catch a rare glimpse of an endangered condor. To Sammy, the trip is nothing more than the painful in pursuit of the unspeakably ugly.
But when she and two other girls find an injured condor, Sammy's intrigued at last. As they track down a clue, they stumble onto two classmates and wind up lost. Which leaves three girls and two boys in a canyon with one tent and six billion biting flies. Oh—and an armed and dangerous high stakes poacher.
S'mores anyone?

Sammy Keyes is a pre-teen spitfire, a tomboy Nancy Drew who loves adventure. In 'Wild Things' she finds herself camping at a Condor reserve; a bird gets shot, and she and her friends (including love interest Casey) track down the culprit. Obstacles in their way: poison oak, a blabbermouth mom, and some serious blisters are only the beginning. Grade 5 - for advanced vocab and the boyfriend (very mild).

Really liked this one! Although the ending showdown was a bit much.
