Solid Conclusion. This is Book 3 of a quick novella series - no one book is much more than 100 pages, and the back 2 are under that mark - and as such both of the prior books should be read first. Though at least in this one, that isn't as imperative as in the second book. Even though the timelines continue to coincide, there is not as much from the first two books that directly shows here as there was in the 2nd book, mostly due to the more limited number of appearances of these two primary characters in the first two. But this does finally get us to the Valentine's Dance that is the official "big reveal" of the series, and even manages to tie back to (and provide minor spoilers of) the book that this series serves as a spinoff of. Very much recommended.
