A slight disappointment. Very few technical details this time, and the plot reminiscent of any crime thriller out there. Tension is not equally distributed throughout the novel - for most of the time not much is happening, with an unexpected cummulation of events towards the end. The background facts about the state of science aged a bit (the novel is set in 1971), but not very badly. Overall, too much on the medical side to my liking - if you get nauseated when seeing blood this novel might be too much for you. Also, some of the voices the narrator puts on sound awful - it's like listening to heavily drugged or deranged people (think Gollum's voice from LotR movies).
The background research and content of this book are fascinating and thought provoking, but the story is crammed with technical information to give Harry, the main protagonist, context. As a story the book is interesting, but very slow and laboured. I also felt the main characters actions were flawed and their actions or reactions unbelievable. My willing suspension of disbelief was challenged several times. But, I am still thinking about the consequence of imminent singularity.
