Volcano! [PDF ebook] 

It was supposed to be a fun camping trip. Tom and Kevin had been looking forward to it all summer. Kevin had never camped before, and Tom couldn’t wait to show his friend how to fish and survive in the wilderness. But when the long-dormant volcano erupts, their fun trip vanishes, replaced by a mad dash for survival. Tom and Kevin have to use their smarts to outrun the lava spilling madly from the volcano’s peak.
