However, Lewis was also a prolific writer in other genres, including:
* Christian apologetics: He wrote extensively on the defense of Christian faith, including *Mere Christianity* and *The Problem of Pain*.
* Science fiction: He wrote *Out of the Silent Planet*, *Perelandra*, and *That Hideous Strength*, collectively known as the *Space Trilogy*.
* Literary criticism: He wrote essays and books on literature, including *The Allegory of Love* and *A Preface to Paradise Lost*.
While *The Chronicles of Narnia* is his most recognized work, Lewis's legacy extends beyond children's literature to encompass a broad spectrum of theological, philosophical, and literary contributions.
