The initial prologue drew me in with a thriller setting and hints of some tech to come. The second teaser not so much - it would have played better where it belonged chronologically after having gotten to know the world and our hero. That also would have increased the suspense - I also felt the initial situation was resolved too quickly, and some information could have been delayed a bit. As it was I found the out of sequence chapter annoying rather than engrossing.

Characters were generally well constructed and fleshed out and differentiated well, with good attention to the minor characters.  The development of the characters and relationships followed naturally from their introduction.

The plot was also well constructed and taken competently to the expected conclusion. Except I'd have liked a few more surprises along the way, and particularly by the end I'd have expected to meet the unexpected. There were missed opportunities to build suspense, and the plot could have done with a few more twists to fulfil the thriller/assassination/espionage promise of the opening.

The near future tech was extremely well done, and I'd only have a few developmental suggestions or quibbles. The technological and computing technologies showed evidence of good research and understanding of the state of the art, and few holes re where we might expect to be in a few years time. There were also plenty of imaginative setting details - as well as some clever and natural plotpoints that I'd have missed, like the insurance angle.

Dialogue was in general very tight and appropriate to the character, although there were aspects of the language use that I didn't like and in places the tone was wrong (like an FBI agent saying "said some technical stuff").

There was also the odd joke for the IT insider. All in all a well crafted story that I really enjoyed.

Oh, one technical issue to fix: the verso shows a different title, presumably a working title - I like the current title better.

In summary, I recommend this book to adult and young adult readers, although note that it does include a variety of four letter words (and perhaps more than strictly necessary or character appropriate): Mild+ in terms of language and violence and sexuality.
