Summary

Chapter 21 opens with Sarah Morgan making breakfast for her nine-year-old daughter, Summer, on a morning when Summer is scheduled to visit her father, Bob, in Washington, D.C. Sarah is anxious about the trip because Bob recently threatened her, but she decides not to cancel so that Summer can still enjoy time with her father. While they eat, Summer notices a man working on the deck outside. Sarah explains that she hired Alejandro, a handyman, to repair the deck. Summer asks about Alejandro’s tattoos, and Sarah deflects by saying he chose them. Sarah then shifts the conversation to Summer’s upcoming outing.

After Summer goes to shower and pack, Sarah watches Alejandro work. She feels drawn to him and prepares a plate of food and a glass of orange juice. She brings them outside and they talk. Alejandro explains that his time in prison taught him to eat quickly and that he never wants to return. He reveals that he joined a gang as a young man because he lacked a stable family and was looking for belonging. Sarah responds by saying that he and she are not so different—they both fell into survival mode. The conversation reveals that Sarah endured a traumatic childhood: her father died, her mother turned to drugs, and she survived motel rooms and abuse. Alejandro seems to understand her meaning without further explanation.

Character Development

Sarah Morgan: This chapter deepens Sarah’s backstory. She is shown as a mother who tries to protect her daughter from the reality of the separation, even as she struggles with her own anxieties. Her conversation with Alejandro reveals that she has a past marked by extreme hardship—poverty, drug-addicted mother, and sexual abuse—which she has kept hidden. Sarah’s ability to relate to Alejandro’s experiences shows her capacity for empathy but also hints at the lengths she has gone to survive.

Alejandro: He is more than a simple handyman. He is reflective about his past and honest about the circumstances that led him to prison. By opening up to Sarah, he humanizes himself and creates a bond based on mutual trauma. His comment about not having a choice the first time around echoes Sarah’s own lack of choice in her childhood.

Themes, Symbols, or Motifs

Survival: Central to this chapter is the theme of survival. Sarah and Alejandro both used survival instincts to navigate broken homes and dangerous environments. Sarah frames her entire existence as “survival,” which includes both her marriage and her current actions.

Motherhood vs. Protection: Sarah’s desire to shield Summer from the truth about Bob’s threats and her own past conflicts with her need to be honest. She lies about working and about her feelings, but she allows the visit to go ahead for Summer’s sake.

The Deck as a Metaphor: Alejandro is repairing a deck that has holes and missing boards. This mirrors Sarah’s life—she is attempting to fix what is broken, but the work is ongoing and exposes the damage underneath.

Choice vs. Circumstance: Alejandro says he had no choice when he joined a gang, while Sarah made a choice that led to Adam’s death. The chapter blurs the line between voluntary action and compulsion.

Why This Chapter Matters

Chapter 21 is pivotal because it reveals Sarah’s traumatic past for the first time. It explains why she is so determined to keep Summer safe and why she is capable of extreme actions. The bond forming between Sarah and Alejandro sets up a potential partnership that could affect the plot. Additionally, the chapter paints Sarah as a survivor rather than a villain, complicating the reader’s sympathy.

Study Questions and Answers
