The first three books that I’m listing are three of the best sources. Not only that, but as I was compiling the list, Amazon recommended these three books as being frequently purchased together!
I own all of the books that I’ve listed below (plus all of the Imaginarium Geographica that’s been release so far). Do take a look at all of these books, and you’ll have a much greater understanding of the writers behind the magic of both Narnia and Middle-Earth. One book not listed, which is no longer in print, is The Inklings

The Company They Keep: C. S. Lewis and J. R. R. Tolkien as Writers in Community
The creators of Narnia and Middle-earth, C. S. Lewis and J. R. R. Tolkien, were close friends and professional colleagues. They met frequently with a community of fellow writers at Oxford in the 1930s and 1940s, all sharing their works-in-progress. The group became known as the Inklings.
This important study challenges the standard interpretation that Lewis, Tolkien, Charles Williams, Owen Barfield, and the other Inklings had little influence on one another’s work, drawing on the latest research in composition studies and the sociology of the creative process. Diana Glyer invites readers into the heart of the group, examining diary entries and personal letters and carefully comparing the rough drafts of their manuscripts with their final, published work.
Her analysis not only demonstrates the high level of mutual influence that characterized this writers group but also provides a lively and compelling picture of how writers and other creative artists challenge, correct, and encourage one another as they work together in community.
Tolkien and C.S. Lewis: The Gift of Friendship
They quickly discovered their affinity–a love of language and the imagination, a wide reading in northern myth and fairy tale, a desire to write stories themselves in both poetry and prose. The quality of their literary friendship invites comparisons with those of William Wordsworth and Samuel Taylor Coleridge, William Cowper and John Newton, and G.K. Chesterton and Hillaire Belloc. Both Tolkien and Lewis were central figures in the informal Oxford literary circle, the Inklings.
This book explores their lives, unfolding the extraordinary story of their complex friendship that lasted, with its ups and downs, until Lewis’s death in 1963. Despite their differences–differences of temperament, spiritual emphasis, and view of their storytelling art–what united them was much stronger, a shared vision that continues to inspire their millions of readers throughout the world.

Fiction
Looking for the King: An Inklings Novel
Aided by the Inklings-that illustrious circle of scholars and writers made famous by its two most prolific members, C.S. Lewis and J.R.R. Tolkien-Tom and Laura begin to suspect that the fabled Spear of Destiny, the lance that pierced the side of Christ on the cross, is hidden somewhere in England.
Tom discovers that Laura has been having mysterious dreams, which seem to be related to the subject of his research, and, though doubtful of her visions, he hires her as an assistant. Heeding the insights and advice of the Inklings, while becoming aware of being shadowed by powerful and secretive foes who would claim the spear as their own, Tom and Laura end up on a thrilling treasure hunt that crisscrosses the English countryside and leads beyond a search for the elusive relics of Camelot into the depths of the human heart and soul.
Weaving his fast-paced narrative with conversation based on the works of the Inklings, author David Downing offers a vivid portrait of Oxford and draws a welcome glimpse into the personalities and ideas of Lewis and Tolkien, while never losing sight of his action-packed adventure story and its two very appealing main characters.
