Birch Tree Publishing is a prominent publisher of unofficial Minecraft-themed books, catering to both young readers and adults. Since 2015, the company has focused on the growing popularity of Minecraft, leading to the release of various titles, including Zombie Kid and The Giants of Stonehold by Mark Cheverton. The first illustrated Minecraft novel, The Great War, was released in October 2023, receiving positive feedback. Birch Tree has plans for six more Zombie Kid novels and additional titles scheduled for late 2024. Their Minecraft books are distributed through major retailers like Barnes & Noble, Target, and Walmart. Birch Tree has evolved from a one-man operation in the late '90s to a full-service publisher, utilizing a hybrid model of publishing contracts.
