seattle trip reading suggestions?

I have a small list of books compiled for the two-week trip out to Washington and back. Are there any other books that should be on this list? Here's what I have so far:

Radical by David Platt Cold Sassy Tree by Olive Ann Burns The Pursuit of God by A.W. Tozer O Pioneers! by Willa Cather Till We Have Faces by C.S. Lewis

What others should I check out?
