Light of the World
– Peter Seewald's interview with the Pope – is an interesting book. It gives insights into what the Holy Father thinks on a variety of issues. Since it's an interview, it makes for easier reading than his heavier books (Introduction to Christianity, Jesus of Nazareth).
It's also available
for Kindle. Kindle has a great text-to-speech feature, so I enjoyed listening to the book on the ferry today.
