Franklin W. Dixon 
Will to Survive 

Frank and Joe are an accident waiting to happen when they go undercover to expose sabotage! The Shorewood Nature Center is a beautiful place to hike…to learn about local ecology…or to fall off a cliff. The Hardys learn that the hard way when they go undercover to investigate strange happenings on the grounds. In no time at all, they get jumped, smoked out, and booby-trapped. The Hardys have never run from a challenge, and theyre not about to start now. Someone will do anything to shut the center down, and Frank and Joe have a clue why: theres a secret buried somewhere on the centers groundsa very valuable secret thats worth a lot more than the lives of two young detectives!
