Query: This is a waste of time!

This book was so bad, I couldn't believe I stayed up all night to finish it. I should have just caught up on my sleep! It was a complete waste of time. The vampire-theme was interesting at first, but it quickly fizzled. And the ending chapters about the "Mastermind" was really bad...I don't know if I'll ever attempt another James Patterson book after this.I would have given it less than a 1 if I could have.
