What are some good books written in the form of journal entries?
Can't believe no one had said The Martian yet. It plays, Masterfully, with the tripe odd journal entry novels, by being a transcript of video journals. It's also a very realistic book, and redefines hard Sci fi with the voice of the current generation. Could not recommend nore highly.
Jakob Von Gunten by Robert Walser.
Anyone who recommends The Martian should always bring a huge disclaimer. The character development and writing is awful. The only thing interesting (and very much so) is the scenario and MacGyver in space.
But the fucking lol-so-quirky ninjarobots space pirate disco shit is terrible.
