Just so you know, nothing about the quoted bits seems trollish. Four days is more than long enough to read a novel, and some people don't look at the excerpts.
I looked at the review and the reviewer. What's suspicious is that you only have a Kindle version, but the review isn't for an Amazon Verified Purchase. The reviewer has but this single review to his name. It already has one positive up-vote the day he posted it. In my experience, for a book ranked close to 200,000 with only two Amazon sales, that's a bit unusual. So, yeah, it's suspicious.
Possibly he reviewed the wrong book. Or he's a mean person. Or he purchased a paper copy and legitimately disliked it. Much as it hurts, you have to allow for that possibility. (My favorite book by my favorite writer has 52 one-star reviews, so there are at least 52 idiots writing reviews
)
If you haven't contacted bloggers for reviews, now would be a good time. Maybe a Goodreads giveaway? Assuming that's not against the Amazon Prime rules.
