I'm a librarian who loves anime, manga, and reading a wide variety of genres.
As long as I don't think too hard about how fast the romance has progressed, I like it. Lonely heroine who thinks she's doomed to have everyone she loves leave her, hero who wants a place where he's needed and welcomed. But yeah, it really doesn't make sense that they've fallen all over each other so fast, even considering that they'd met a few times prior to this book. It only took maybe a day for the kissing and heated looks to start.
The non-romance storyline is nice because it ties in with an overarching series plotline that I'd thought Owens might save for the end of the series, although a quick Goodreads check indicates that it's going to take another 8 books for Vinni and Avellana to be old enough to star in their own book. I'm not sure how I feel about a romance novel starring characters that were first introduced in the series as children.
