The Solution
K. A. Applegate
 After having a bizarre dream, Rachel is woken by Ax, who explains Jake's express orders to summon her. That decision bothers her, but her qualms are silenced when Ax breaks her the news of Tobias's probable death. Rachel is willing to do what Jake expected her to do. They fly to Marco's house. Ax tries to fly through his window, but is promptly knocked out by Marco. Or rather, David in Marco's morph. Rachel allows David to morph to golden eagle, and leads him on a chase through town. Rachel plans to lure him into the power lines, electrocuting him. But David outmaneuvers her, and almost kills her. Fortunately, David is attacked by a hawk, which turns out to be Tobias, with David thinking that it is a random red-tailed hawk. Relieved that Tobias is alive, the Animorphs plan how to trap the traitor. At school, they're surprised, though, when David, in Marco's body, demands the Blue Box, threatening to betray their identities to the Yeerks. Cassie tries to reason with him, but to no avail. Making no progress, David leaves, with Rachel in pursuit. In a secluded spot on the school grounds, Rachel tells him that even if David betrays them, she'd still have time to make short work of him and his parents before she would be silenced by the Yeerks. David tries to attack her, but she pins him down. Having made her threat, she releases him. Soon after, Rachel becomes enraged with the way Jake is manipulating her violent tendencies. The Animorphs formulate one final attempt to doom the Yeerks' plan to make controllers of some of the G8 leaders. They morph dolphins and travel to the shore of the Marriott resort. Then they morph elephants and rhinoceroses, and ravage the resort huts the heads of state reside in. They leave a screaming Visser Three in 'Tony's' morph, and retreat into the ocean. The plan is a success, but they encounter David, in orca morph. Here David accuses Rachel of threatening to kill his family, and Rachel is hurt by her teammates' silence. After an exhausting battle, Cassie morphs into a humpback whale and drives David away. Rachel collapses in her bed the next morning, but is almost immediately pestered by her sister Jordan, wanting some comfort regarding Saddler's grave condition. Rachel walks into the bathroom, and is confronted by an invisible David. He challenges her to a personal war, which she accepts. Rachel then accuses Jake of not standing with her against David, and that Jake thinks she is a psycopath. At the hospital, the family visits their dying child. It becomes apparent that he is far from dying; he'd somehow miraculously made a full recovery. Jake immediately suspects David. When the three of them are alone, David mocks Rachel and Jake, demanding the Blue Box. Rachel and Jake reconcile, and then begin concocting a scheme to beat David at his own game. The Animorphs have a mock discussion about a Blue Box that breaks into smaller pieces, and Rachel pretends to have been morally defeated by David, being mocked by Marco the whole time. They meet David at a Taco Bell, and agree to lead him to the Blue Box, allowing him to abuse Rachel some more. Rachel and David fly to the abandoned construction site, with the other Animorphs following close behind. David traps the Animorphs as cockroaches in a Pepsi bottle, and he and Rachel morph rats. They venture into the pipes to retrieve each 'piece'. David soon figures out the Animorphs' elaborate trap, and Rachel tries to escape, barely doing so. The instant she escapes, a cage door is dropped, trapping David. Tobias swoops down and reveals to David that he is in fact, still alive and freed the other Animorphs from the bottle. Rachel and the others decide to let David be trapped forever as a rat. Cassie had plotted out all of David's emotions, gauged his inflating ego, and knew the sociopath would select Rachel as his victim. Rachel and Ax stay behind. Rachel because she says David's anguish won't bother her, and Ax so he can keep track of time and make sure David remains trapped as a rat. Rachel and Ax carry David out to a desolate rocky outcrop a mile offshore (which Rachel had first glimpsed the night they stormed the Marriott resort beach), and leave him, his pleading and cursing trailing behind them. *David is trapped in rat morph. *Saddler dies, likely killed by David. *Rachel realizes that she possesses violent tendencies beyond a simple love of excitement, and that Jake is disturbed and concerned.
