My kids' books are full of treasure hunts, pirates, caves, mountain men, scary monsters, girls, boys, dogs, cats, rats, bats, secret agents/spies, good/bad guys, graveyards, caveboys, dinosaurs, tigers, haunted houses, ghosts, secret passageways, stormy nights and action packed days. There's a lot of jumping, running & screaming. The kids learn to depend on each other and stay alive so I can bring them all back again. These are fun filled, action packed, mystery adventures. You will love them!
