You’ve just had a long, hard, exhausting day, and all you want to do is curl up with something light, fun, easy, fluffy, distracting, and entertaining.
What book do you pick up?
A media tie-in novel would be my first choice here. Possibly something from the Star Trek or Doctor Who universes. Characters I already know and a universe I’m fond of, familiar with and comfortable in. Sounds like a perfect way to wind down from a hard day.
