Looking for a fun book to read this weekend? Right now you can snag the #1 New York Times Bestseller The Girl on the Train: A Novel for only $6.99 (reg. $26.95!).  Janet Maslin of the New York Times says, “The Girl on the Train has more fun with unreliable narration than any chiller since Gone Girl. . . . The Girl on the Train is liable to draw a large, bedazzled readership too. . . . The Girl on the Train is full of back-stabbing, none of it literal.”  Wow!
