The Volcano Disaster — Peg Kehret

What started as a class assignment turns into much more than Warren Spalding and Betsy Tyler had bargained for? In The Volcano Disaster, Warren and Betsy are assigned a project about Mount Saint Hellions, but Warren ends up testing his grandfather's crazy invention --the Instant Commuter. Next thing Warren finds himself in the midst of living history with no escape in sight from the erupting volcano. With Betsy as his only hope, Warren and Betsy begin a race against time to bring Warren back.
