1.We first meet Rachel when she's discovered her daughter is missing. What were your initial impressions of her? How did your perspective evolve?

2. "She's a normal teenager, i.e., moody maybe, but not depressed." These are Rachel's thoughts upon reading Marley's goodbye note on the white board. Does this characterize the Marley you come to know over the course of the book? Is she depressed? If she ordinary, or exceptional? Is Rachel out of touch with who her daughter truly is?

3. "Normal teenagers don't run away. Ergo, she didn't run away," Rachel goes on to think. This exposes the first of many of Rachel's blind spots. If you're a parent yourself, what do you think your blind spots might be? Are we all prone to some forms of denial?

4. What kind of wife is Rachel? What kind of husband is Paul? How do you imagine their marital dynamics shaped Marley and her view of relationships?

5. If Rachel had monitored Marley more closely --- including her social media --- would their story have been different? How do you think social media impacts teens and their ability to connect with each other, their parents, and the world around them?

11. A theme in the novel is visibility. In this social media-saturated world, is it more important to be seen than to be known? To be "liked" (i.e. on Facebook) as opposed to truly liked?

12. "Opposite-speak is different from lying, because when you use it, you always know. You're never trying to fool yourself," Marley writes in her journal, as a way to contrast herself and her mother. "The worst thing you can be is a liar to yourself." Do you agree?

13. Dr. Michael is very important to both Marley and Rachel. Is he a destructive or a constructive force? What do you imagine his intentions to be?
