'Postcard Killers' is an interesting collaboration between Swedish author Liza Marklund and American best-seller James Patterson.

It follows a Swedish journalist and an American cop on a European chase for a mystery couple who trick other couples to private hotel rooms, where they get killed and are posed like famous pieces of art. The killers then send postcards to local newspaper reporters with pictures of their artwork.

While Marklund's previous books are far better, (this is the first I've read by Patterson), it's definitely an easy read. Short, snappy sentences and quick chapters make the book easy to complete in just a few nights.

The book will be released in the U.S. on Aug. 16.
