Pilgrimage: My search for the Real St. Francis by: Mark Shriver (2015)

This book is written by a member of a prominent democratic/ liberal Irish Catholic family about Pope Francis.  The story is inspiring.  He lives an austere life but is generous with those on the margins-- poor, immigrants, etc.  Yet when he becomes Pope he is a celebrity in some respects like other celebrities.  A good story, worth the read.
