Brian is convinced that his cheerful, joking father is still angry at him for accidentally destroying his valuable Superman #1 comic book from 1939. Like his father, Brian collects comics. So he's not surprised when Mr. Somerset, the owner of the town's general store, gives him one. But he is surprised to find that the comic book is full of blank panels and that a metal ring falls out when he opens it. Brian's best friend, Paul, finds a dial on the ring. He sets it to 75 million B.C., presses a button labeled "Timequest," and the boys suddenly find themselves in the middle of the Atlantic Ocean battling a prehistoric beast! They decide to use the ring to travel back to 1939 to get another Superman #1 for Brian's father. But when a string of misadventures threatens to alter their life back at home forever, Brian realizes that the comic doesn't matter as much as getting back to his mom and dad. - from Amzon
