This was a perfectly fine book that I brought for the plane and it did not disappoint. The story follows a computer programmer/painter/PI named K as he tries to untangle the chain of events leading to the murder of a fellow programmer and the extraordinary cover-up that follows. Generally I don’t enjoy books about computers because they seem to get so many thigns wrong, either about how computers work or how tech culture works in general. This book gets enough things right that it doesn’t stand in the way of the storyline. The main character is likable enough and the story is fast-paced enough to keep the pages turning until the end. For a book I knew nothing about except for seeing the word “code” in the title, this was a pleasant surprise.
