This was an absolutely amazing work! I could not stop reading. Extremely well done. I was hooked from the moment I opened it. I will say that the Goodreads description is a much better one than that printed on the back cover of the book. I would definitely suggest not reading the summary on the back, because it reveals a major plot point that the character doesn't discover until about two-thirds of the way through the novel. I'll admit I was very disappointed after having read that summary as it took away from the overall mystery. However, the novel was still phenomenonal and a definite must-read. I loved that Leno seems to actual understand the phenomenon that was the base of her book; it added a great deal to the work. It is difficult to describe exactly what made this book so amazing. It really has everything. This is a true masterpiece.
