For me I am doing my own reading challenge. I want to read 12 books this year. I know not much compared to some of the ones I have seen around but with two kids my reading time is limited. As for what books/genre or what not, it is what ever that happens to be on my shelf that I have not read. I have more then enough to choose from.
So if you are doing a reading challenge what ones are you doing, how many books are you trying to read? Is it a challenge of your own or is it one you entered on a blog or site else where?
