Summary

Fifteen-year-old Andie Delaney works her part-time job at Cara’s Bakehouse in Boulder, Colorado. A regular customer—a tall, bearded man with a limp—engages her in conversation, unusually chatty today. Andie’s boss, Cara, grows protective and questions the man. After leaving, the man crosses the street and watches the café from his white F-150. He is Zack Hightower, former Navy SEAL and CIA officer. In a flashback, Zack recalls a 2009 firefight with Al Qaeda terrorists at a mall, where he killed three attackers and executed the wounded leader. After the attack, his wife Tiffany feared for their daughter Stacy (now Andie). To protect them, Zack entered them into the Federal Witness Protection Program. He later divorced Tiffany, who remarried and changed her name to Jennifer; Stacy became Andrea “Andie.” Zack has spent years secretly watching his daughter. Now, a nerve-jolting leg injury from a recent mission reminds him of his wounds. He gets a call from CIA handler Matthew Hanley, who orders him to Norfolk for an urgent operation. Zack leaves Boulder, vowing to stay away from Andie.

Key Events

  1. Andie serves a regular customer – The man orders “coffee, large, three sugars, and a cheese Danish,” which Andie remembers.
  2. The man initiates small talk – He asks about her age, school, and work, making Andie slightly uncomfortable.
  3. Cara intervenes protectively – She steps in, watching the man until he drives off, then warns Andie about him.
  4. The man parks across the street – He watches the café from his truck, revealing himself as Zack Hightower.
  5. Zack’s memory of the mall shooting – He recalls leading a counterterrorism hit in Eritrea, then being targeted by Al Qaeda. In La Jolla mall he killed three terrorists, finishing by shooting one in the groin.
  6. Divorce and witness protection – After the attack, Zack and Tiffany agreed to put Stacy (Andie) into WITSEC. He divorced, joined the CIA, and later used contacts to track his ex-wife and daughter.
  7. Zack’s current life – He now works as a contract agent for the CIA, recovering from a gunshot wound. He came to Boulder under the pretext of seeing a doctor but actually to watch Andie.
  8. Phone call from Hanley – CIA officer Matthew Hanley summons Zack to Norfolk for an urgent mission. Zack agrees to leave immediately.
  9. Zack’s internal conflict – He struggles with guilt and pain, realizing he has no real claim to Andie. He forces himself to drive away.

Character Development

  • Andie Delaney – A bright, friendly fifteen-year-old who enjoys her job and dreams of Olympic snowboarding. She is trusting but perceptive, noting the customer’s unusual talkativeness. Her boss’s suspicion hints at her naivety regarding danger.
  • Zack Hightower – A hardened warrior haunted by his past. His surveillance of Andie reveals deep guilt and a desperate need for connection, yet he knows he is a stranger to her. His physical pain mirrors his emotional torment. His decision to leave when called shows his professional discipline overriding personal desire.
  • Cara – Protective mother-figure; her immediate distrust of Zack underscores the danger that Andie does not sense.
  • Matthew Hanley – Off-page, but his call reinforces Zack’s identity as an operative; he is a handler who can summon Zack back to the shadows.

Themes, Symbols, or Motifs

  • Hidden Identity – Zack’s disguise as a friendly cowboy contrasts his violent past; Andie’s new name and life represent the erasure of her origin.
  • Guilt and Atonement – Zack’s hunt for his daughter is driven by remorse for giving her up; he seeks forgiveness without confessing.
  • Protection vs. Stalking – Cara’s protective stance and Zack’s clandestine watching blur the line between care and obsession.
  • Pain as Memory – The recurring nerve pain in Zack’s leg serves as a physical reminder of his recent mission and his emotional wounds.
  • The Unseen Past – The chapter uses flashback to reveal how a family was shattered by violence and secrecy.

Why This Chapter Matters

Chapter Sixteen deepens Zack Hightower’s backstory, revealing the personal cost of his career as a covert operative. It shifts the emotional stakes from action to intimacy: Zack’s mission is no longer a government operation but a private pilgrimage. The chapter also sets up his departure from Boulder, implying that he will soon be pulled back into a new crisis, directly impacting the plot’s forward momentum. By humanizing Zack through his paternal longing, Greaney raises the question of whether an operative can ever truly leave his past behind.

Study Questions and Answers

1. Why does Zack watch Andie from across the street instead of approaching her?
Zack knows that Andie’s life is stable and happy under witness protection. Approaching her would risk her safety and his own promise to stay away. He believes that any direct contact would make him “look like a creep” and could expose her true identity.

2. How does the mall flashback explain Zack’s current emotional state?
The flashback shows that Zack’s violence was both professional and personal—he executed a wounded terrorist in retribution. That moment fractured his family and led to the witness protection arrangement. The guilt and rage from that incident still drive his need to see Andie, as he seeks a connection he voluntarily severed.

3. What does Cara’s reaction to Zack reveal about the theme of protection?
Cara’s immediate suspicion of Zack highlights the instinct to shield the young from unseen threats. Her action mirrors the witness protection system itself: both are protective mechanisms that rely on vigilance and distrust of outsiders. Her wariness contrasts with Andie’s innocence, emphasizing the theme of hidden dangers.
