The Return is the forty-eighth book in the Animorphs series, written by K.A. Applegate. It is known to have been ghostwritten by Kimberly Morris. Due to an editorial oversight, Lisa Harkrader was mistakenly credited with writing the book. It is the final book to be narrated only by Rachel and is the first of the last seven books to have an inverted title, in which the main title is in color and the background of the title is in black, showing a definite change.
David, the "sixth Animorph," is back. When the Animorphs and Ax decided to give another human being the power to morph, it was one of their biggest mistakes. David tried to destroy all of them - and almost succeeded. Rachel and the others thought they'd seen the last of him when they trapped David as a nothlit. Leaving him on a deserted island to live out his days as a rat...
They were wrong.
Rachel knows what a threat David is. He's cunning and dangerous. Worst of all, he knows their secrets. Now he's captured Rachel as part of his plan to take over everything. David wants power. Money. But more than anything, he wants revenge...
The book begins with a cold open into Rachel's dream-within-a-dream to give the impression of reality; the Animorphs are taking a tour of the White House just as the Yeerks launch an attack. Hork-Bajir and Taxxons try to prevent the President from being airlifted away from the scene, but Rachel attacks them and lets the helicopter fly off. Jake approaches her and tells her that he had already told her to de-morph and stay out of the fight, as she was badly injured, but Rachel tells him not to tell her what to do. They have a brief fight for superiority, and Rachel is defeated as she is bleeding to death, however immediately awakens (at the time, believing she has actually awoken from the whole dream) screaming after thinking a stream of blood rather than sweat is running down her cheek.
Following this are a succession of events in the dream, including: Marco, Ax, Tobias and Rachel at Ax's scoop discussing their current situation and the Yeerks' plans, as well as stories appearing on the Internet of first-hand accounts of Yeerk battles (which Rachel notes as actually happening in the real world) and Rachel feeling victimized and set apart by the others for her opinions; Tobias and Rachel flying over the forest, further talking about Rachel's attitude to battle, with Tobias clarifying that "I don't think anyone really understands where you're coming from." Rachel then finally wakes for school, and attends but feels disillusioned and disconnected from everyone and everything; asking Cassie to meet her after school at her farm, Rachel walks to Cassie's barn but is set upon by a large pack of rats, as is Cassie.
It is eventually revealed that this strange event was a manipulation of reality by Crayak, the recurring red light in her dreams and at school. With the help of Crayak, David , the boy who betrayed the Animorphs after being recruited to the team, has returned for revenge on Rachel after she trapped him in rat form (explaining the recurrence of rats earlier). As part of the manipulation of (but still) reality, Rachel awakens in a small cube underground, and David is set in front of her outside the cube by two teenagers. He brags to her about commanding an army of rats to escape from the island, climbing into a boat which belonged to scientists counting the bird population, and doing all sorts of deeds for him once making it back to the mainland, including swarming Rachel and Cassie at her farm. He also claims to have stolen hundreds of thousands of dollars since being trapped as a rat by getting into places no human can. He says this is how he has bribed the two teenagers to bring him to Rachel. He also brags and tries to manipulate and sway Rachel, telling her she is a bully for what she did to him, and showing her a locked-up Cassie and forcing Rachel to morph to rat to become a nothlit like him or Cassie will suffocate. Soon Crayak arrives, and Rachel concludes that David has for the most part been lying about his exploits, and he admits he has, and that he has been brought to her by Crayak. The Drode, who has accompanied Crayak, reveals, however, that David's desire for revenge is not their reason for appearing to Rachel.
Crayak intimidates Rachel and shows her what she could be (a far more powerful, taller version of herself with retractable metal claws and all kinds of advanced reflexes) if she accepts his offer to be a leader and stop the Yeerk invasion of Earth; all she has to do is kill Jake. She says "I am one of the good guys," but Crayak tries to sway her by switching her between her rat morph (fighting with David) and "Super-Rachel". He then brings Visser One to her, and they fight, with Rachel triumphing until Crayak switches realities again as Rachel refuses to eliminate him. He and the Drode eventually disappear, calling her a fool and a coward, and insisting she is weak for not living up to her potential.
Rachel appears back in rat morph, but convinces the two teenagers, offering them David's fake stashed cash as a reward, to free her just in time for her to de-morph. They escape when she morphs to grizzly to scare them. David also tries escaping, and Rachel frees Cassie, but tells her to leave without her, telling her she is going after David. Ultimately failing to escape after Rachel follows him, David finds himself in Rachel's clutches again and he begs her to kill him, insisting putting him back on the island would be a fate worse than death. David's ultimate fate is unexplained.

|Visser One||--||Acid Monster, Liquid Monster|
- Rachel "morphs" into several creatures that do not exist except in the world manipulated by Crayak and the Drode, including a giant, ambulatory venus flytrap, and a gigantic version of herself with "mechanical claws" and superhuman strength.
- The cover quote is, "The sixth Animorph is back, and he's not happy..."
- The inside cover quote is, "Rachel's really hit the big time..."
- Of the Animorphs, only Rachel and Cassie appear in any real-time events. Jake, Tobias, Marco, and Ax only appear in Rachel's dreams, but are otherwise absent.
- When Rachel morphs into a gigantic version of herself with "mechanical claws" and superhuman strength, it may be a reference to the Howlers.
- Also, when Cassie tried to get away from the rats, she was said to be morphing. It is unknown what she was morphing.
- A highly anticipated book by the fans, David finally returns here after 24 books, having his supposedly last appearance in #22: The Solution.
- Crayak's interest in Rachel is fully played out here as he tries to bring her to his side by giving her ultimate raw power. This storyline begins as early as #6: The Capture when Crayak (known only as Big Red Eye at the time) notices Jake when his Yeerk dies, and it isn't until #26: The Attack when Crayak comes to have a new found hate for Jake after his Howler race has been destroyed. Crayak then tries to kill Jake in Megamorphs #3: Elfangor's Secret, but yet again, fails.
Crayak, from that point on, then sets his sights on Rachel to get to Jake, and uses his minion The Drode to do the job. The Drode then makes a brief appearance in the next book #27: The Exposed and yet again in Megamorphs #4: Back to Before, however, it isn't until here that they finally try to persuade Rachel into betraying Jake, in favour of giving her the power to defeat Visser Three.
- The fate of David at the end of this book is debated by many fans over and over, as it is left open to speculate. Either ending is possible in its own way and neither are confirmed nor denied by K.A. The ending is, however, briefly touched upon again by Cassie in #50: The Ultimate when they begin to discuss recruitment.There, Rachel is immediately against the idea and reminds them of David. Cassie (to herself) acknowledges the history they had with David, including the events that unfolded here in this book with Rachel and David, but she too is unsure about whether Rachel had killed him in the end or not, and speculated that it is something that Rachel would never tell her either.
- ANIBASE: The cover of this book features Rachel becoming "Super Rachel", a hyped up version of herself. To create Super Rachel, cover artist David Mattingly hired a female body-builder to pose for the body, then he pasted an image of the Rachel model's face on top of it!
