"The Mythmakers" explores the friendship between C.S. Lewis and J.R.R. Tolkien, from their childhoods and traumatic war experiences to their meeting at Oxford and the influence of their bond on fantasy literature. It highlights their creative differences, shared ideas about mythology, and the role of their literary group, the Inklings. The book uses a mix of prose, comic panels, and conversation between a wizard and a lion to explain complex ideas. Key themes include world-building, the value of fantasy, faith, and the impact of their works on modern storytelling.
