Returning to Superstition Mountain, the Barker brothers, along with their friend Delilah, soon find themselves entangled in more danger and mystery as they uncover a treasure. Illustrations.

It's summer and the three Barker brothers—Simon, Henry, and Jack—just moved from Illinois to Arizona. Their parents have warned them repeatedly not to explore Superstition Mountain, which is near their home. But when their cat Josie goes missing, they see no other choice. There's something unusually creepy about the mountain and after the boys find three human skulls, they grow determined to uncover the mystery. Have people really gone missing over the years, and could there be someone or some thing lurking in the woods? Together with their new neighbor Delilah, the Barker boys are dead-set on cracking the case even if it means putting themselves in harm's way. Here's the first book in an action-packed mystery series by a New York Times bestselling author. Missing on Superstition Mountain is a Publishers Weekly Best Children's Fiction title for 2011.

Relates legend, lore, and fact concerning the Lost Dutchman gold mine of south-central Arizona.

In pioneer lore, the Lost Dutchman's Mine remains an intriguing mystery of the Old West. What became Apache Junction in the Salt River Valley was already an established home for prehistoric Native Americans and the Apache tribe, when it was further settled and cultivated by Spanish and Mexican expeditions, American wagon trains, mountain men, and the U.S. military in the late 19th century. But Apache Junction became legendary when German immigrant Jacob Waltz discovered a secret gold mine. Thousands of prospectors traversed the "crooked top" Superstition Mountains in search of this treasure, enriching the area's history and leading to the development of a unique community that has endured and grown alongside the famous legend.

The Barker brothers and their friend Delilah secretly climb up to Superstition Mountain one last time, hoping to solve the remaining mysteries, including whether the librarian is really the ghost of Julia Thomas, what was their uncle Hank's role in discovering the gold mine, and especially, who is trying to kill them.
