Hello! I plan on starting my first Camino in September 2019: any thoughts on a book that you felt was worth its weight to carry? I am not interested in taking a kindle, or reading from my phone. I was thinking about something from John O'Donohue; or maybe the Pilgrimage book by Phil Cousineau? I would love to hear if anyone really felt the book they carried was enlightening and not just extra weight. Thanks!
