Mountain of Bones

by Christopher Krovatin

Published 11 September 2012
When Ian, Kendra, and PJ are separated from their class on a school hiking trip in the mountains, the unthinkable happens: they come face-to-face with a legion of terrifying zombies. They don't know where they are. They don't know how to get home. They don't know what gruesome creatures lurk in the shadows-but when they find out, will they be able to defeat these monsters and escape the mountain together? Perfect for tween readers who are aging out of R.L. Stine's scary chapter book series, Gravediggers: Mountain of Bones is a mysterious, wild ride that will thrill readers to the very last page.
