⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

Letty Davenport wakes from a nightmare about breaking up with her boyfriend Jackson Nyberg. Lucas Davenport calls with urgent news: the woman seen with Richard Foss at the Taos supermarket, Danielle Callister, has been spotted driving a green Subaru SUV through a checkpoint heading south toward Santa Fe. Lucas dispatches Letty, Alec Hawkins, and Barb Cartwright to intercept her at the Santa Fe airport before she can board a flight and potentially spread a deadly virus.

The team races to the airport. Letty devises a plan: she and Hawkins will enter the terminal carrying a suitcase to appear like travelers, while Cartwright positions herself on a dirt pile with a sniper rifle. Inside, Letty alerts airport staff and security to stay calm. Callister arrives, towing luggage from the RV. Letty and Hawkins step outside to confront her. Callister, a former tree-sitting activist, reaches for a fanny pack containing virus vials. When she opens it, Letty calls "Green light," and Cartwright shoots Callister dead with a single rifle shot.

Immediately after, Santa Fe police arrive. Letty identifies herself as Homeland Security and explains the situation. The cops reveal that word has already leaked that "germ people" are being hunted, a development that alarms Lucas when Letty calls him afterward.

Letty and Hawkins confront Callister outside the terminal.
Callister reaches for the fanny pack, Letty gives the "green light" command, and Cartwright kills Callister with a headshot.
Santa Fe police arrive; one officer already knows about the "germ people" investigation.
Letty calls Lucas to report the kill and the leak.

Character Development

Letty Davenport demonstrates sharp tactical thinking, quick leadership, and emotional control under pressure. She remains composed during the kill and the aftermath, despite the grotesque nature of the shooting.
Alec Hawkins shows vulnerability; he is visibly shaken by the violence and struggles to "buck up" as Cartwright orders. His earlier instinct about Callister's arrival proves correct, hinting at his intuitive side.
Barb Cartwright is unflappable and professional. She executes the shot without hesitation and later remains stoic, criticizing Hawkins's reaction. Her bond with Letty is evident in their seamless coordination.
Danielle Callister is given a brief backstory: a former environmental activist with a history of run-ins with the law. Her final words express belief in saving Gaia, underscoring her ideological commitment. She hesitates but ultimately chooses to open the fanny pack.
Scott (cult leader) speaks to Callister on the phone, ambiguously telling her she'll "live forever." He also reveals that he and Clarice plan to flee Taos.

Themes, Symbols, or Motifs

Sacrifice vs. Terrorism: Callister views herself as Joan of Arc sacrificing for the planet. The narrative frames her as a terrorist willing to kill millions. This contrast challenges readers to consider the boundary between ideological martyrdom and mass murder.
Split-Second Decision-Making: The chapter revolves around a moment of judgment—Letty gives the kill order based on Callister opening the fanny pack. The moral weight of that decision is seen in Hawkins's horror and Letty's quiet acknowledgment that the call was correct.
The Fragility of Secrecy: The leak to police ("Is this one of the germ people?") signals that the operation can no longer remain covert. Lucas's crude reaction ("Fuck me with a barbed-wire fence pole") underscores the new danger: public panic.
Guns as Tools, Not Fantasy: The kill is described unglamorously—not like the movies—highlighting the grim reality of lethal force.

Why This Chapter Matters

This chapter brings the pursuit of Danielle Callister to a violent climax and removes one of the three vectors carrying the virus. It also introduces a major complication: the media or law enforcement leak that threatens to spark widespread panic in Taos and beyond. Letty's leadership here cements her role as a capable field operative in her own right, separate from Lucas. The chapter sets up the next phase of the hunt for Scott and Clarice, who now know the net is closing and may try desperate escape routes.

Study Questions and Answers

1. Why does Letty give the command "Green light" to shoot Callister?
Letty sees Callister open the Velcro on her fanny pack and reach for the vials inside. She judges that there is no more time for talk and that Callister intends to break or release the virus. The risk of an airborne release in a public terminal is too great, so she authorizes lethal force. The decision is tactical, not vengeful.

2. What does Scott mean when he tells Callister, "You'll live forever"?
The line is deliberately ambiguous. On one level, Scott may be promising her that her name will be remembered by survivors if the plague succeeds. On another, it may hint that he expects her to die in the attempt, becoming a martyr. Callister herself worries about ending "like Joan of Arc," burned at the stake—suggesting Scott's words are not reassurance but manipulation.

3. How does the police leak affect the rest of the operation?
When the local cops already know about "germ people," Lucas realizes the story is spreading. This means Scott and Clarice may hear the news and alter their escape plans. It also raises the possibility of public panic or interference from local authorities who may not follow federal protocols. Lucas immediately tells Letty to call Greet (likely a superior) to mobilize more resources.
