Surprise!

I knew nothing about this book and read the first chapter sample on the Kindle. I couldn't stop reading it. It was the literary equivalent of Memento or the Usual Suspects where you had to constantly be realigning your understanding of what was going on. It's three separate storylines that become interwoven in the end. Very clever.
The fun too was since I read it on the Kindle I had no physical measure of how much further the book was going. I was too involved in the story to keep an eye on the percentage on the bottom of the screen.  I had just figured everything out and ---pouf---it was over!
