Jarring
You know how some people spend a lot of time on playlists (the same type of people who used to spend a lot of time on mix tapes)? They want to get the right songs in the right order because it matters. There’s a scene in High Fidelity (book and movie) where the main character talks about that.
I have never been that kind of person, and it shows most blatantly in my book choices. Occasionally I’ll pick a book because I’m looking for a certain kind of experience (one year, I timed it so that I would be reading a book by Robin McKinley on my birthday because I knew I would love it and I wanted to be reading something I’d love on my birthday), but that choice (or any other book choice I make) almost never has anything to do with the book I just finished. It leads to some pretty abrupt transitions.
Case in point: today, I finished a light and lovely book about two girls making their debuts in society in Regency England. A few hours later, I started book 5 in a series about an alien invasion and the soldiers who have to fight them in space.
Keeps me on my toes.
