The Dinosaur That Followed Me Home — Bruce Coville

TALK ABOUT TALL TALES!
Last summer at Camp Haunted Hills, Stuart was kidnapped by a bigfoot, chased by a mummy, and stalked by werewolves. So why should this summer be any different?

Stuart's wildest imaginings can't match what happens this time around at the outrageous movie camp run by Hollywood's hottest director. While filming a movie at camp set in the prehistoric era, Stuart and his friends are accidentally blasted into the past! When they finally return to the present, three dinosaurs come along for the ride! Stuart must get the dinosaurs back to their own age, or it could be curtains for life as we know it. Can the campers blast them back to the past -- and keep the dinosaurs a really big secret until they do?
