Lost at sea, you find yourself stranded on a mysterious island. You immediately run into a treacherous triceratops and a man-eating mastodon--and realize you are lost in time! You must find a way to escape. A helpful caveman named Ralph tells you about a magic homing device hidden in a far-off cave. But you'll have to keep your wits about you and your eyes open if you hope to find the device--and survive.
That shadowy form in the tree above you, for instance. Could it be the murderous saber tooth tiger you've been warned about? What do you see? If you curl into a ball and hope it ignores you, turn to page 24. If you jump into a nearby pit to get away, turn to page 33. Only you can make the choices that will lead to your freedom--or to your destruction!
