If you haven't read the book
"Heaven is for Real", by Todd Burpo,
I would recommend it to you. It's a light read
but interesting. The movie was not very good.
An old favorite book of mine, though not particularly christian, is
"The Long Walk", by Slavomir Rawicz
It's a true story of survival and endurance. It has
plenty of dark moments, and you really can't put
it down.
