I liked reading this book. Fast paced action, an appealing if imperfect hero, at the cutting edge of computers, society, and security. A quick read that kept me turning pages.
I am still disappointed. Where is the Cory Doctorow of "Walkaway"? Or "Radicalized"? The protagonist in this story seems to be a guy who is feeling his age and still has sympathies for progressive ideas but has (sort of) made peace with things as they are. Though I think the ending is worth reading a couple of times. At first it sounds a bit obvious and some have thought it tone-deaf, but I think it is self-consciously so.Cory Doctorow intends his speculative fiction to be "at the very edge of the present". This one feels less at the edge. More like a modern thriller than speculative fiction, he's just slotted there.
Maybe he will stretch Martin Hench in future books. But it kind of doesn't look that way.
