Query: An intelligent, thought provoking and compulsive read.

This book is one of the few I will read over and over again, because of the many layers it has. And also because it made my heart beat faster, as if I were on the verge of a great discovery. Each layer tells its own story and gives you something to think about.(It certainly made me think)And so it makes the total more than the sum of its layers. Absolutely great reading! This book is not about incestuous relationships, it is certainly not silly, it is not confusing and it is certainly believable because the characters are well rounded and consistent in their actions. By being able to write such a complex story, the writer will (alas) attract the jealousy and the spite of less gifted writers or readers who are simply not intelligent enough to comprehend the scope of this work.
