I just created a list titled "Books to come back to" listing, you guessed it, books that I haven't finished but would like to though they're not on my priority list anymore.
I'm currently working on several books from the library, but all are approaching that final renewal category. There are so many books I have in my own library that haven't been finished and (worse still) have never been read that I really feel the pull to make a dent in that stash before I continue to yank books left and right off of the shelves.
In the mean time, I've chosen a few from my library stash (and the one I most recently requested -- it took me two months to get it because there was a wait) to keep trucking along with - one I'm enjoying in spite of it's slower pace, one I love because it's a memoir, and the last is my current read ("Eating Animals," by Jonathan Safran Foer).
Alex tells me I'm not quitting because I have plans to come back to them. I'll stand by that answer . . .
