An Honest Man by Michael Koryta

 

This is an excellent novel, a cluttered story with clear characters; through the middle section it's more interested in unveiling a couple of the characters than in unveiling the plot/s they're dedicated to unraveling, but that's OK: They both have secrets they're skittering around the edges of, and telling the reader those secrets makes them--especially the main POV character--much more reliable, even as like tight-third-person narrators. Other than those characters being somewhat veiled, especially at first, and some other characters being intentionally murky as to their morality and/or trustworthiness, everyone's motivations are pretty clear, here. Koryta seems to have a thing for the physical edges of the US, between the North Atlantic and Montana; the metaphors there seem pretty obvious to me and they might even be intentional.
