With no alternative, Marco tells his father about the Yeerk invasion of Earth, the role he has played in the war, and tells him that they can no longer return home, even to save his wife, Nora. Marco also finally reveals the fate of his mother, Eva, telling his father that she is the host of Visser One.After hiding his father with the Chee, Marco speaks with the other Animorphs at Cassie's barn and tells them of what has transpired. Rachel suggests using the Z-Space transmitter created by Peter to intercept Yeerk transmissions, but the device is currently in the custody of the Yeerks. Ax is enlisted to help Peter re-build the transmitter.Meanwhile, Erek King and his "father" are posing as Marco and Peter at Marco's former home.

The Yeerks briefly speak to Nora, who has since been infested, and she follows the Controllers off the property. After verifying that the coast is clear, Marco, who was hiding in the house as a cockroach, demorphs and Erek shuts down the hologram hiding himself and Mr. King. Erek takes minimal damage in the Yeerk assault, but Mr. King needs more extensive repairs. Erek carries Mr. King back to their home disguised as a garbage truck, leaving Marco alone to contemplate what his life will be like until the end of the war.Animorphs is an English language science fiction series of young adult books written by K. A. Applegate and published by Scholastic. It is told in first person, with all 6 main characters taking turns narrating the books through their own perspectives. Horror, war, dehumanization, sanity, morality, innocence, leadership, freedom, and growing up are the core motifs of the series.The story revolves around five humans, Jake, Marco, Cassie, Rachel, and Tobias, and one alien, Aximili-Esgarrouth-Isthill (nicknamed Ax), who obtain the ability to morph into any animal they touch. Naming themselves "Animorphs" (a portmanteau of "animal morphers") they use their ability to battle a secret alien infiltration of Earth by a race called the Yeerks. The Yeerks are a parasitic race of aliens resembling large slugs that take humans as a host by entering and merging with their brain through the ear canal. The Animorphs fight as a guerilla force against the Yeerks, led by Visser Three, and their program to take over the human race. Morphing into animals allows them to battle the various armies of aliens that the Yeerks use, but it also protects their identities. As far as the Yeerks know, only Andalites like Ax have the ability to morph, and if they knew that the Animorphs were mostly human they would be able to easily find out who they are. Protecting their identities becomes more and more difficult as the series goes on because though someone with the ability to morph can change into any animal that they touch, they can only stay in a morph for two hours or they will permanently become that animal. Throughout the series, we see how the war affects the characters in different ways, mentally and physically.
