The Seventh Most Important Thing

I loved this book and it had one of the best plots I've read in a long time. I'm not usually a fan of books in which a main character uses a list (or keys, or doodads from a dead relative, etc) to go out and find themselves, but it really worked here. I believed this story could have actually happened, especially when we discover what the Junk Man's secret is. No spoilers here.
This would make a great book club selection as there is much to discuss!
