During my 8 days or so of no power I read quite a lot of books, mostly in a bathtub filled with cold water.
I read the first 3 books of the Drizzt saga by R.A. Salvatore. Very enjoyable classic fantasy books.
I also read all 6 of the Dexter books by Jeff Lindsay. Simply awesome. The same characters you know from the show (mostly) but after the 1st book the storyline forks off in very different directions.
Then I read the first 2 books of the Jack Nightingale series by Stephen Leather, wasn't expecting all that much but I ended up really liking them. Very predictable though.
I also read a big old Calvin & Hobbes compilation book I have had forever. Easily the best comic strip ever. Plus the complete Trigun collection, one of my favorite Manga.
That's pretty much it, besides maybe 3 or 4 other books that weren't worth mentioning in this fine thread.
You would be amazed how fast books fly by when you have absolutely nothing else to do.
