Wow.  This book was a hard read.  Not in the difficulty of the writing but in the subject matter.  The main character's journey is one of pain and suffering.  It is not a world that is too hard to imagine, though I hope it never comes to pass.  The political messages in the book are clear and present.  This book could serve as a warning for what could happen should Americans choose to turn a blind eye to immigration, climate change, and rhetoric rather than working to help and solve problems in a peaceful and inviting way.
