It's a clever concept, but Lewis' writing vastly improved in his later works.
Minor: Racism
My main take-away from this book was something that changed my perspective on the "journey to heaven". In very short summary , Lewis demonstrated that our journey before God from our first impression looks similar to how we view our lives, but then when we take a second look and see the spiritual side that God views us from, it all looks very different. Everything that we come into contact with in life that takes us away from God (people, places, life events), making us sinful, doesn't exist in the way God views us and in how we will see our own life journey upon reaching the afterlife. God sees what is most important. And that's it. What he sees is you traveling towards him and the goodness and wisdom you encounter through it all. The difficulty of the journey and the life lessons learned from it isn't taken away. But the bad is gone. It remains on earth where you left it.
