Moving. At first I thought this was going to be about the value of going with the flow and letting go of irrational fears and inhibitions that prevent people from achieving their full potential and/or pursuing their passions. It was kind of about that. But it was also about not that at all. It was about how going with the flow can lead to complete and total beat-downs; punishments so brutal that you forget who you are and lose your identity.
The imagery of the sky and the power of the unknown that lies beyond our living perception was haunting. This book also made me want to go to old-timey northern Africa.
Oh, and the main character dies in the middle of the book. Very different and refreshing. I love unhappy endings! Really, I do.
