Making a List (of Books)...

We're leaving on vacation soon, and I can't decide which books to bring with me. Here's what I've got on my shelf:

1) The Rosie Project
2) Lookaway, Lookaway (this one's definitely coming along)
3) I Heart New York
4) A Tale for the Time Being
5) The Golem and the Jinni
6) I-Mary, a Biography of Mary Austin (This is for work, and I probably won't open it the whole time. At least it will get to do some traveling, though.)

What should I bring...?
