It’s a direct sequel to WALLS and follows the adventures of my protagonists, John Rayburn, his doppelganger John Prime, and his friends Grace and Henry. The end of book 1 found the four trapped in Universe 7651 after escaping the Alarians in Universe 7650. They’ve built a new device in 7651 to return home, only to find that the Alarians have found the first gate John built. But now with the ability to build transfer gates between universes, the Pinball Wizards start building a transdimensional company, one that uses differences between universes as ways to make money and use ideas.
