Which book should I read?

I am going out of town for a few days by myself (grandma's memorial service) and have lots of airplane/airport time and thought I might tackle one of these books I have laying around that I never have time to read. But can't decide which to read. None of them are grabbing me but I am sure they would be good. Anyone want to recommend one?

Life of Pi by Yann Martel
Long Way Down by Nick Hornby
Broken Music by Sting
Homesick by Sela Ward
Confederacy of Dunces by John Kennedy Toole
