Reuleaux's Portal. The Sophont Trilogy, #3

Alice had her looking-glass. Holly has Reuleaux's Portal. Coppélia seems different, somehow. Karen's granddaughter, Holly Bryson, notices some discrepancies between her grandmother's video-memories and those of the android. The records should be identical, but they're not.  Something doesn't add up. An incredible conclusion is drawn, but it's still only a hypothesis and needs to be proven or disproven.
As Captain of the Space Cruiser, Sir Isaac Newton, Holly, her Chief Medical Officer husband, Simon, and Coppélia, set off on a rescue mission that leads to their ship inadvertently passing through Reuleaux's Portal and into a world that they would never have thought possible in their wildest dreams. What should have been a simple rescue mission turns into an experience that defies the laws of physics, as the crew of the Sir Isaac Newton are caught in the middle of a struggle between androids and a technophobic human regime.
