Shotgun Beginning Focuses Into Laser Ending. This is one of those stories that opens up with a lot of moving parts, even as we only really get a single perspective of them, so it can be a bit difficult of a read to get into at first. Compelling, to be sure, particularly the accident during the blizzard, but through these intro sections the tale doesn't seem to know what it wants to be yet... and thus the reader may find it difficult to follow.
This noted, as the story progresses, things become ever more clear and pointed and the book finally decides what it wants to be... and oh, boy. Absolutely several interesting twists here, both within the story and in how the story itself subverts expectations of the reader.
Ultimately this is going to be one of those stories that seems like a bit of a challenge up front, even if compelling, but stick with it long enough for the tale to figure itself out. Because once it does, you're in for a fun time indeed.
Very much recommended.
