English fantasy writer and J.R.R. Tolkien is widely considered to the be the father of the modern fantasy genre. The Hobbit and The Lord of the Rings trilogy are some of the most enduring and beloved novels in the genre. In the years since readers were first introduced to Middle Earth (The Hobbit was published in 1937), the novels have served as in inspiration to countless writers, filmmakers, video game creators, and even the creator of the Dungeons & Dragons tabletop role playing game. His most famous works have remained in print since their publication, and even some of his lesser-known posthumous publications have garnered attention. For example, The Silmarillion, a history of the mythology of Middle Earth, won the Locus Award for Best Fantasy in 1978. One volume that has remained mostly under the radar, however, is the charming Tree and Leaf. What exactly about this book makes it such a treasure?
