Bookroo's summary
Ax, the Animorphs' alien ally, is gravely ill, and a hospital is not an option. As Cassie and her friends scramble for a solution, they face a daunting task: infiltrating the dangerous Yeerk pool. But when Jake, Rachel, Tobias, and Marco also fall sick, Cassie must navigate this perilous mission alone. Can she save her friends and Ax before it's too late, or will the virus claim them all? The stakes are high, and time is running out in this thrilling race against an unseen enemy.
From the publisher
Something is very wrong with Ax. He’s sick. And the Animorphs don’t know what to do about it. They can’t take him to a hospital. They don’t know how to contact the Andalite home world. And Ax is dying.
Cassie and the other Animorphs come up with a plan. But it involves finding a new way into the Yeerk pool. There’s just one problem: Jake, Rachel, Tobias, and Marco come down with Ax’s sickness. And now, for the first time, Cassie is on her own. . . .
