Mercy Me!

This just in, one of SK's books made a "cameo" on Mercy (NBC).  My mom watches the show and she told me that one of the nurses was reading one of SK's books.  She said it was 800 pages and started with a "S".  (She's not too familiar with Stephen King's books, unfortunately.)  We determined that it was probably The Stand.  I am trying to get a confirmation of which book at this time.  Once I get confirmation I will post here, it may take some time to track this down.
