Yellow Blue Tibia by Adam Roberts started out slow, a dull and relatively uninteresting plod through the initial set up of the novel and the brief review of the narrator's life between then and the latter events of the novel. Thankfully it gets better from there. The narrator is a clever old bastard that maintains a level of wit that would only be described by the people he goes up against as exasperating--for the reader it is a pleasure to read and oft times outright hilarious. I would not go so far as to say that characterization is a strong suit for the novel, the supporting characters (even the most minor) are all colorful, but none are ever fully explored and I would have to say that the main character isn't either. Still, it is the very minor one-shot characters that sometimes bring about some of the most entertaining scenes in the novel.
For the majority of the novel the story is rather straight forward, though it does venture into the weird at some points. Somewhere around page two hundred is where things go odd. Not extremely odd, mind you, there is a degree of normalcy retained for most of the remaining pages of the novel. Until we get to the final chapter, to the Coda. This is when Roberts discovered that his weird goes to eleven and things go insane. Everything is revealed in a mostly vague manner and we learn what could quite possibly be the truth (because on the other hand we have to keep in mind that the narrator is 69 years old, drank more than the average Russian for a significant portion of his lifetime, and has radioactive shrapnel embedded in his skull and may or may not just be utterly delusional).
Yellow Blue Tibia is a good read and entertaining, but I wouldn't go so far as to call it one of the better novels I have read this year. The pacing and short length lends to making it a quick read and I have feeling most people could finish it off in a sitting or two.
