An old friend recently asked me if C.S. Lewis' Cosmic Trilogy (also know as the Space Trilogy ) would make it into my top 100 list. My response was 'Yes, it would'. Masterpieces such as The Screwtape Letters , The Chronicles of Narnia and Mere Christianity still stand as some of the best Christian writings since John wrapped up the book of Revelation. But nestled somewhere in Lewis’ back catalog are three books that remain somewhat obscure and are simply referred to as the ' Space Trilogy.' The result is a work that is much more complicated than a single reading can capture but also one that is rewarding beyond words for any reader willing to seek out these books. These books capture Lewis at the top of his creative game and his ability to distill his favorite themes and ideas into the universe. [1]
