Freedom is a theme that runs throughout Tom Robbins' wild adventure featuring Sissy Hankshaw, a woman born with enormous thumbs that help her become a perpetual woman in motion.  Her journey brings her in full contact with many unique characters across a vast American landscape of sexuality, language, ideas, adventure, and identity.  The unrestrained writing style might be summarized as:

I believe in everything; nothing is sacred.
I believe in nothing; everything is sacred.
Ha ha ho ho and hee hee.

Dr. Robbins
