Missing on Superstition Mountain certainly lives up to its name. There have been a lot of mysterious deaths of people who have gone up there looking for a giant gold mine. Sam, Henry, and Jack Barker and their neighbor Delilah make a bad mistake when they go up the mountain. They find three skulls up on a ledge and soon the police are involved. It's a mystery book. I was kind of disappointed when the kids found a map, but never found the gold mine. Now that I know this book is part of a series, I can't wait to get the next story.
