Giant telepathic companion cats! If nothing else kept my attention in this novel, those would. Thankfully, the world and supporting cast also kept me awake. I will admit that my eyes started to glaze over nearly any time they mentioned quantum mechanics or the concept of time as a non-linear function. My brain is not good enough to wrap itself around those concepts. Fortunately, there were enough fantasy elements to keep my slow little mind engaged despite the hard-to-reach science.
