To replace another of the artifacts they accidentally destroyed, Grant and Ash must travel further back in time than ever before—ten thousand years, to Paleolithic Virginia Beach. They quickly realize that in this time, food doesn't come from a supermarket, and if they want to survive, they'll need to learn skills like hunting and fire-making.

Merlin's magic won't return them to their time until they locate a mammoth talisman, but this time, they'll need to do more than find the object. They'll have to earn it—along with their manhood names—in a dangerous hunt. And before their latest adventure ends, they'll have to help an injured young man and convince two rival tribes to work together. It might be a different environment, but they soon see that human hatred and fear are universal. Luckily, so are love and compassion.
