Grendel Easter Egg - Zodiac in Every Chapter

If you read the book, Grendel, you'll notice it has exactely 12 chapters. In each chapter, the author makes a reference to one of the signs of the zodiac, starting with Ares, Taurus, Gemini, etc. The book is very symbolic and I wouldn't be surprised if there was more than just that in it. If you do read this, you should pay attention for other little things the author put in.
