My new book, The Screwtape Letters Handbook is now available!

While THE SCREWTAPE LETI’ERS may be enjoyed simply as a creative work of fiction, Lewis weaves many profound truths into the correspondence between a senior devil and his protégé. This handbook helps mine those insights by providing detailed letter outlines and an easy-to-use topical glossary.

ENDORSEMENTS:
