"This was my family. My brother, the killer. My father, the target. And me, the fool in the middle. Just the three of us. If my brother Tom, in a desperate, last-ditch attempt to save himself, tried to kill my father, then I would morph. And the last thing my brother would see was me, his brother, his unknown enemy, rear up and destroy him with all the ruthless, savage power that was mine to command. I had told myself that I would do whatever had to be done, and I would."

The Conspiracy, published in June 1999 and written by Laura Battyanyi-Wiess based on an outline by K.A. Applegate and Michael Grant, is the thirty-first book in the Animorphs series. It is the eleventh book narrated by Jake and his seventh book as sole narrator.


Official Description[]

Jake's grandfather has died. It blows the family away -- especially Jake's mom. So Jake's parents decide they should all travel to the grandfather's home to help with the arrangements. In another state. For three or four days.

This is a very big problem for Jake's brother, Tom. He can't be away from the Yeerk pool for that long. So Tom refuses to go -- and his father insists. But Tom's Yeerk will do anything to survive. Including making his father less of a problem.

Now Jake, the other Animorphs, and Ax have to find a way to protect his father without Tom discovering their secret. And without having to choose between his father's life... and Tom's.

Major/Highlighted Events[]

  • Jake's great-grandfather, Grandpa G, passes away, prompting the family to leave town for four days in order to attend the funeral. This presents an issue for Tom, since his Yeerk cannot survive four days without Kandrona rays.
  • Tom's Yeerk decides to have his host body's father infested, which Jake is against, unwilling to lose another family member to the Yeerks.
  • After Marco prevents Jake's father from being infested, Tom has Chapman and a few other human-Controllers attempt a drive-by to assassinate Jake's father, although they are stopped by Jake.
  • The Animorphs kidnap Chapman and Jake asks Ax to torture him before allowing him to escape. Following the ordeal, Ax temporarily drops the "Prince" honorific, telling Jake that he would never do such a thing again, angry that Jake made him commit torture for personal reasons over the war effort.
  • Forced to go to the cabin, Tom decides to use a knife to kill his father in the middle of the night, prompting Jake to morph into his Siberian tiger to kill Tom. However, as Jake was too emotionally invested, Marco takes over as temporary leader and formulates a plan, which involves Rachel and Ax breaking Tom's leg, forcing Tom to be transferred to the city hospital, where he would have access to Kandrona rays.
  • Marco explains that as interim leader, his number one priority was ensuring the safety and security of the Animorphs, and admits that he was willing to allow Jake's father to die to do so. However, upon realizing that Jake would not have accepted his father being killed but could tolerate Tom's death, Marco divulges that he had a contingency plan where he would kill Tom without making it seem like the "Andalite bandits" were involved, prompting Jake to realize that he and Marco have changed drastically since joining the war.
  • Rachel reveals that she is related to Jake through his father. Since Jake's family stated in The Solution that Rachel's mother Naomi was only related by marriage, this would mean that Rachel's father Dan and Jake's father are brothers.
    • Additionally, Rachel discloses in Elfangor's Secret that her father is Jewish, meaning that Jake's father is Jewish as well.

  • Marco's attempt to kill his mother in The Reunion is referenced and paralleled with Jake's decision to deal with his father and brother.
