Here is your official guide to the Star Wars Legends books in chronological order. Months before the first Star Wars movie hit theaters in 1977, readers were introduced to George Lucas’ galaxy far, far away through the novelization in 1976. When the film became a massive hit, the franchise continued to expand through original novels, including Alan Dean Foster’s Splinter of the Mind’s Eye, written to be adapted as a low-budget movie if needed. The modern Star Wars Expanded Universe truly kicked off in 1991 with Timothy Zahn’s Heir to the Empire, the first novel of the bestselling Thrawn trilogy.
