Reading Slump, Any Ideas?

[Siuan]

Lately I find myself in a reading slump. Usually my genre of choice is fantasy/sci-fi, romance/historical fiction and some thrillers thrown in for good measure. But lately I just can't seem to find a book that will grab my attention and keep so that I can't put the book down, everything's gotten a bit predictable and that frustrates me a little (a lot really especially for the thriller genre), as I like a good plot twist and big reveal to have an impact. What do you guys do when this happens to you? Do you find a new genre to try for awhile or do you look for a new activity to do and try to read after some more time passes?
