Congratulations to our third winner, White Pearl! We hope you'll love Astronomy Hacks! Whether you're a first timer or an advanced hobbyist, you'll find Astronomy Hacks both useful and fun. So, it's day four of our five-day give-away week and for today we chose a very special book. It's from our mechanical team lead Jürgen Brandner, called Blutprinz and it's about Vampires. But it differs a lot from Twilight. So, if you can read German, this book is well worth a read. If you're eager to get your hands on this book, just go to our facebook page, "like" our wall post and maybe you're the lucky one to get this book for free!
