Ever since the book “The Girl With the Dragon Tattoo” and its sequels became such monster hits, it seems every other book on the best-seller list has the world “girl” in the title. “Gone Girl,” “The Girl on the Train,” “Gadget Girl,” “The Windup Girl,” and of course, Amy Schumer’s “The Girl With the Lower Back Tattoo.” According to one of the book trade magazines, 364 books with the word “girl” in the title have come out in the last eight years, with 80 this year alone.
