Unity

We know from the cover of this book that a giant mech-style robot is going to come into play. But getting from the opening chaos of our central character being woken up and shoved on a transport plane - that subsequently crashes - to the robot is quite a ride indeed. With UNITY, Robinson has taken us into one of his most developed and novel worlds yet. Technically this could be classed as YA due to the characters' ages, but don't let that fool you - this is one excellent ride, cover to cover, no matter what brand of technothriller/ scifi / dystopia you like. (And don't let even that fool you - if you want an excellent story, period, this is the book for you.)
