I just remembered another book that I read in the spring that didn't get reviewed. This book was pretty sleazy and is one I would have quit if I'd have had anything to read. I took a book with me to Cedar City when I went to help my sister after her operation. My mistake was not taking it to the hospital. In my defense, I didn't know I'd be staying all night but after the operation both my sister and I felt I should stay. Luckily she had a book she thought she'd feel good enough to read. She didn't.
The one good thing about Postcard Killers was that it kept my interest piqued throughout the night and I was able to stay awake. Being one of James Patterson's, the chapters were short and the writing a bit large. Many would have finished it in a few hours - it took me most of the night.
Do I recommend it? Not really. There's too many descent books that are really good to waste time of this type of read under normal circumstances.
