Overall, this is a great book. The story is creative, the writing is clean and evocative, and the plot was inexorable and never stale. Some may take issue with the lack of punctuation around dialogue, or "time travel plot holes,"... to those people I say, you're not seeing the forest for the trees. To those who are willing to chance a read, here are aspects I enjoyed: 

-This is basically ASMR in book form. The descriptive text, including metaphors, adjectives, and adverbs, are vivid and unctuous. 
-I did not hate how this male author wrote a 1st person story from a female perspective. 
-I LOVED how this sci-fi story, complete with seemingly good guys and bad guys, totalitarianism, and time travel, was so tangible. The book is based around realistic people, in a town I've probably visited, in a setting that is very familiar. If not possible, Howard at least makes me think the story is plausible. 
-I admire the courage it took for Howard to end the story with clarity. I very much enjoy Inception-like endings that force you to consider multiple possibilities, but there's something satisfying in knowing how a story concludes.

I also admire the courage it takes to subvert a storytelling trope, and to do so deftly. There is some discussion about time travel paradoxes and how interfering in Ouest 1 may, or could, affect those in town. Howard allows older Odile to interfere, alludes to its effect in her town, and explicitly explains why older Odile is not wiped off the face of the Earth. In so doing, we're led to understand why there is no paradox. It's neither "right" nor is it "wrong," it's just Howard's version, and I like it.
