Invisible by James Patterson and David Ellis

Another amazing cannot-put-it-down work by Mr. Patterson.  This one follows Emily, who I adore, as she pieces together a puzzle only she believes is even a puzzle!  I loved the twist of our main character being the only one who believes in this creep, I loved the ending, and I love James Patterson.  With over 200 books to his name and countless authors clamoring to share the byline with him, he hasn't lost his touch at all.  Highly recommended for mystery, thriller, or Patterson fans everywhere.
