Yes, this is only a free preview, but it is available as a "Read It Now" format and as a PDF file, and also available as an audio book. Here is the link to the download page:

The audio preview covers Chapters 1-25, and the PDF preview gives you Chapters 1-30. That does sound impressive, but keep in mind, that's a James Patterson book, so it's only about 100 pages.

Still, that's a good chunk. However, if you want to find out what happens, the e-book is $14.95.
I'm more interested in this book than in most of the James Patterson books because his co-writer is Liza Marklund, a best-selling crime novelist in Sweden. A couple of her books are available in e-book format in the U.S. already. (I'd really rather just read one of her solo novels to see whether I like them, but those have been a harder to find, and this book is everywhere.
