The Product Details section clearly states that this is in German.
Unfortunately i cant seem to find an English version that doesn't cost a lot of cash. I urge you to search the net for the audio of this on Scott Sigler's website. It is awesome, I loved it. Most enjoyable Sci Fi book, for me, since Rendezvous With Rama.
This book has an original storyline with a very good plot. The characters are so detailed you can build an exact picture of them. The story keeps moving and does not falter at any point. Gripping throughout.
I ordered this book from the UK and it turned out to be the German copy. There was no written information on the web page that this is a foreign language copy. Only if you blow up the photo of the book do you see that it is another language.
