Duke and Miguel are part of a research team devoted to laying the foundations of interstellar wormhole travel. During a shower of asteroid fragments, their maintenance pod is damaged and they are unable to escape the gravity of the black hole they are studying.

After falling through a synthetic black hole that swallowed the planet Jupiter, they arrived in a fantasy world of strange creatures and magic. Now they are forced to fight for their survival relying on their wits and the resources they can find at hand. The two 21st century interworld travelers will be hard pressed to avoid becoming prey to man eating plants, shadow wolves and numerous other dangers as they explore this new world known as Peridia. Nobody said it would be easy to start over from zero while avoiding the notice of a fire breathing dragon.

Can two lost travelers navigate the pitfalls and hazards of Peridia? Will they master the secrets of this mysterious new world or succumb to its peril? Will they have to travel to the ends of this new world to find their way back to Earth? The answers can only be found after traveling Through Jupiter's Door, the first book in the Black Hole Traveler's saga.
