Once comfortable with routine, Marcus now seeks adventure. He quits his job, dumps his boyfriend, and buys a one-way ticket to Spain. Life could not be better.

On his way to the airport, Marcus almost hits someone running across the road. Curiosity gets the better of him, and he follows the person to a mysterious cave with a secret, one that transports Marcus to a prehistoric world.

Dazed and definitely confused, Marcus is trying to find his way back when he’s saved from imminent danger by the ruggedly handsome Jade, a caveman whose face and body belong on the cover of a romance novel. Jade guides Marcus back to the cave and, along the way, the unlikely pair may just discover each has found his perfect match. But when danger strikes, Marcus must decide where his heart truly belongs.
