What do you like to read for mindless pleasure?

The thing is, I don't do anything for mindless pleasure. So, if I can't think of anything better, I'll pull out Harry Potter and read it for the millionth time. I very nearly memorized it. You can ask me almost any question about the series, and I'll give you a right answer, and maybe an explanation. That story never gets old. Never.

Either a really good love story or a really thrilling drama adventure. Kind of opposites but i love 'em!

200 page love story books I have read before. Things like forever by judy blume or meg cabot books. Especially after a heartbreak!

Fanfiction (sometimes it's better than 'real literature') or some fantasy (e.g. the Inheritance cycle, the Nightrunner series). :)
Everyone needs a break sometimes. I can hardly believe that you read Proust or Joyce all the time. It is somewhat ironic that I'm listening to Tchaikovsky while writing this answer . :D

Anything by Sophie Kinsella (shopaholic series writer)
Or
anything from Piers Anthony's Xanth Series lol

Manga XD
And also diary-style books.
