Memories with Maya is both good scifi and a relationship story with a twist. I wanted to keep reading to find out what happened next to the three main characters. I found Dan a bit irritating at first, where he doesn't express his feeling for his girlfriend Maya, but he comes through in the last third of the book.
I also learned many interesting ideas and applications of Virtual Reality and Augmented Reality (think more advanced than Google glasses) that I hadn't come across before. The book is an eye opener into what will soon be possible with this kind of technology and the social implications. From enhanced nightclub interactions and virtual clothing, to lie detecting glasses and remote reality sex encounters. Then there are the military applications that get Dan and Maya into serious danger...
Also worth taking a look at is some of the science behind the story. The author posts this at at http://www.dirrogate.com (but if you don't like spoilers, visit the site after reading the book!) and he has also written on the transhumanist aspects of VR.
