Yes, I read The Salmon of Doubt: Hitchhiking the Galaxy One Last Time because it features the work of Douglas Adams. Most of this book is just a collection of essays and other unpublished material by the author, but it also has the incomplete novel, "The Salmon of Doubt" in it. It's an interesting albeit sad read if you are a fan of Douglas Adams and it is clear that the author still had a lot of work left to do on it. It is said that Adams wasn't happy with the story and wanted to shift it so that instead of it being a Dirk Gently book, it would be the conclusion to the Hitchhiker's Guide to the Galaxy series. If you are not a fan of Douglas Adams then there's nothing for you in this book, but for everyone who eagerly waited for everything he ever released, it's a fitting farewell to an incredibly talented writer.
