4 Reasons You Must Read The Girl on the Train

Amy is Gone Girl's villain, but she's not 100 percent unrelatable. Flynn gives her a couple memorable diatribes about "Cool Girls," and her motivation stems from an all-too-common marital betrayal: infidelity. That's part of the reason many readers felt conflicted about sympathizing with her: she had her reasons. The Girl on the Train's protagonist is Rachel, and though she's a totally different personality type than Amy, she has some big flaws. You won't initially see yourself in Rachel, but as the book unfolds, there will be times you'll totally get her.
