The Broken Universe
THE BROKEN UNIVERSE begins with the conclusion of the first book in the series, THE WALLS OF THE UNIVERSE. John, Grace, Henry, and John’s doppelganger have been trapped in a parallel universe while they try to build dimension-hopping transfer device. It takes them six weeks and when they finally get back to their home universe, they find that the Alarians have had time to exploit John’s work on his homemade transfer device.
John and his team have got to stop them before they use the transfer device to unleash themselves upon the multiverse. Along the way, John, Casey, Henry, and Grace recruit an army of their doppelgangers to help them build a transdimensional company.
