I might argue about there being no danger of overdosing: ever stayed up half the night reading just one more chapter? Yes, and then the baby woke to be fed at it gets more difficult as you get older but the addiction is still there, ALWAYS.
The Hiding Place by Corrie ten Boom. One of the best books I've ever read...definitely in my top 10. God's hand in the life of Corrie, her family, and their mission was so supernatural. Definitely a must read.
