Black Rock Brothers

"If you like Hank, you'll like Wilder Good, too."--John R. Erickson, author of Hank the Cowdog Every boy has it in his soul to make the big trip. Alone, into the wild. Wilder feels the call after reading about an obsidian deposit on a forgotten bluff in the Spanish Peaks Wilderness. If he can find the glassy, black, volcanic rock, he'll be able to replace his family's most cherished heirloom. Wilder wants to prove that he can make the journey alone, but his parents make him bring his best friend Big, and a new kid called Corndog. With no adults to turn to, can the three boys face the rigors of the outdoors--and each other?
