Normally I'm all for conciseness, but this is one of those rare cases where I feel like a good novel is missing out on the depth of detail that could have made it a great book.
The concept is intriguing, the characters are solid, the mystery and the action move well. The plot and pacing held my attention; I didn't see it coming until it happened, but the "loaded gun on the mantelpiece" comes into play at the end and the climactic scenes deliver.
Car chases! Political terrorists! Dirty cops! All of this in a really neat, future Detroit where highway laws require four passengers and paid hitchhikers or "fourths" are a fixture of the cityscape.
I'm waffling over giving this three stars or four, but ultimately, I really wanted more. There were half a dozen moments where the scarcity of detail pulled me out of the book and left me confused--not only because I had trouble picturing the scene, but also because moments in conversations didn't make sense to me without some context or explanation. I wanted more detail about the technology and the time period in the first few chapters, but instead we're swept immediately into the story in a way that left me feeling like some of the tech was added as scenery and not fully fleshed out. For a book that, ultimately, is about the main character's love of his city, I feel like I didn't really get to know Detroit at all.
A quick, light, engaging read that will probably appeal more to mystery/thriller lovers than to fans of SFF.
