The book was written in 1981 and deals with Luke Skywalker and Princess Leia answering a distress call to find a ship that’s crash-landed, including a survivor who is a potential Jedi.
The issue was written prior to Star Wars: The Return of the Jedi, nevermind the current trilogy, so if you really want to read it, and you can find it, you’re safe from spoilers.
Issue #49 of the original run of the Star Wars comic book does share a title with the next movie in the saga, but we’re fairly certain that’s the only thing the two have in common.
