Applegate Katherine Alice. The Animorphs 34. The Prophecy

The book is known to have been ghostwritten by Melinda Metz.Cassie comes home in owl morph to find a Hork-Bajir leaving the barn. Cassie realizes that if the Hork-Bajir is a Controller, the Yeerks might suspect that she is one of the "Andalite bandits". She attacks it, and nearly blinds him with her talons when she realizes it is in fact Jara Hamee. When she asks why he is there, he tells her that an Arn has come to the Hork-Bajir valley, and Toby wishes for their advice on what to do. Cassie tells the other Animorphs about the Arn the next day and they all agree to go.The Arn's name is Quafijinivon, the last of the Arns. He tells them that he wishes to create a force of Hork-Bajir to fight the Yeerks on their home world, by taking a sample of each Hork-Bajir's DNA. The Hork-Bajirs accept, but Quafijinivon also wishes to find a stash of weapons hidden by Aldrea - Seerow's Daughter. They ask him how will he do this if she is dead, and he tells them about the ixcila of Aldrea he preserved, an electronic copy of her personality, thoughts, and brainwaves. The Arn says Aldrea must choose a host to enter, and they decide it will be either Rachel, because of her dangerous attitude, or Toby because she is her granddaughter. During the Atafalxical ceremony Cassie is chosen as the host instead, she is asked if she accepts and Jake shouts "No". Cassie feels she has no choice, and says yes.The Chee take their place as humans while they're gone. When they make to the Hork-Bajir solar system, the ship is attacked by another Andalite ship. They cannot contact the ship because the Yeerks will pick up their signal. Ax refuses to fire back at the ship because he says he cannot attack a fellow Andalite for doing his job. Jake asks if Aldrea can do it and she says yes. She fires at the ship and destroys the engines, saving them. More Bug Fighters show up and Marco suggest that they move on, but Ax begs Jake to save the Andalite. Jake says they cannot leave, and they assist in destroying the Bug Fighters. Jake cuts the ensuing celebration short so they can focus on the task at hand.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.
