That's a great question! There are lots of good German language books around. Of course, it all depends what you're level is right now. Looking at your profile it seems you are still somewhere at the start which means that you're probably restricted in what you understand. As such I would recommend to stick to maybe children's books, e.g. Michael Ende's Jim Knopf or books by Janosch. The last one is also popular with adults. If you want "proper" stories you could try and find "Heftromane", e.g. the series of Jerry Cotton crime stories or the John Sinclair horror novels (not too horrific). These are generally 64 pages, published weekly and written in normal but not too demanding German. (High literature they sure ain't. LOL) The downside: They are usually only on sale in German railway stations and difficult to get outside of Germany. Some, however, may also be available in eFormat. Here e,g, is one that can be ordered to download for free: http://www.thalia.de/shop/ebooks_kostenlos/rubrikartikel/der_hexer_01/wolfgang_hohlbein/ISBN3-8387-2167-5/ID33289131.html Last but not least: Look for "zweisprachige Bücher", i.e. books that are available both in English and German for parallel reading.
