This one pretty much floored me. The scope and the way this was written kinda blew my mind. 
 What do I mean? Well, it's one hell of an accomplished SF... encompassing all time and space from a single viewpoint in what may as well be god... but isn't. 
 It's a love story with a very complicated relationship of an alien with another alien, it's a love story with time, physics, genetics, and all sorts of real math. I will admit that a very great deal of my enjoyment of this novel stems from the fact that I'm conversant with real science in a big way and this book incorporates it all very heavily in the narrative. 
 The book is kinda like this: think of five or six hella great popular science writers, turn them into short-story writers, let it have the feel of Marvel or DC cosmic-stage stories, and then have it feel right at home with Neil Gaiman's Sandman. 
 I'm not joking. It's really that good and that odd. And while the science bits and how it's written is very heavy in a way, I don't think it overwhelms the actual stories at all. It's unusual and it's very smart, but I wouldn't let that deter you from reading it. Indeed, I think everyone should read this and have it be a solid staple of the mind. 
 My only complaint might be a bit idiotic. I really think these stories would translate perfectly into a real comic. I know it's kinda implied in the title, but still... I think it would be improved, making it even more readable and brilliant... that is, assuming that the artist is up to snuff. :)
