If you read one book this year …

On his Facebook page, Mike Kennedy comments:

If you only read one book this year — seriously — this should be it. Kathleen read ( “When Breath Becomes Air” by Paul Kalanithi ), and encouraged me to read it. It’s incredibly profound and important and humbling and personal. It’s a quick read, and a very important one. Highly recommend.

Question: If you were to recommend one book that a person should read this year, what would it be?
