Kids and Hardy Boys fans of all ages would enjoy Sidetracked to Danger. One of the better later Hardy Boys paperbacks -- the tight requirements did noticeably limit the writer in several scenes, but the story was fun to read and a few twists made it interesting and unique. Loved the trains. My son read this book at the library and begged me to request it here. I can't give any of the post-Wanderer paperbacks (after #85) 5 stars, but this one actually might be close.
