This was a very enjoyable and fast read. It had the same vibe as Little Brother (although LB has more political/ philosophical weight) with a protagonist who is uber-smart, geeky and struggling against social inequity and 'forces of darkness'. The adventures and puzzles he faces and the solutions he comes up with are all very satisfying and I didn't mind that it side-stepped the problem of how to fix up the real world portrayed in the book. Oh and for a person like me 'of a certain age' I loved all the Eighties references, in fact I'm digging out my DVD of War Games right now...
