Gregory Simpson liked Allison Bubar's review of Quantum Time: "Jack and Sarah are back! “Quantum Time" follows Jack and Sarah through time and space. Simpson explains complicated ideas like quantum physics, time travel and parallel universes in a fun way that's easy to understand. "

Gregory’s Quotes

“But, when you were ready to sell them, you had to know there are bad people out there ready to buy them, right?” She tilted her head as she looked for a hint that he was clued in to that. Stephen sighed. “This is why we beta test. Usually it doesn’t go this badly.” Julia imagined that a little homogenous group of techies probably never pulled their heads out of their groupthink to imagine nightmare scenarios. It was an argument for having diversity in those goddamned meetings.”
― E.W. Doc Parris, The Dent in the Universe: Book One of the Epic WalrusTech Universe
