The Perils of Tsundoku

The problem, when you finish reading one book, is that you must choose a new one to start. For most people that isn't a problem, but I, alas, am a victim/practicioner of tsundoku.  For those of you who don't know what that is, it's the practice of acquiring and stacking books that you intend to read at some future point.
I have several stacks of books, scattered about my bedroom. And I have absolutely no idea what to read next.
The current candidates are:
Shambhala: The Sacred Path of the Warrior by Chogyam Trungpa
The Windup Girl by Paolo Bacigalupi
and Magic Lessons by Alice Hoffman.
Any suggestions as to which to read next?
