The war between the Yeerks and the Animorphs is still raging. There are no more secrets - but there are plenty of lies. The kids are fighting harder than they ever thought they could. And they’re about to make the biggest decision they’ve ever had to face. A decision that may eventually break them all.
Ax and the Animorphs have known that the ultimate destruction of the Yeerk pool will give them a huge chance to take back Earth. And they've figured out a way to do it. But there’s no way to destroy the pool without destroying everyone else that may be there. And there’s no more time to think about it. There’s only yes or no...

- ANIBASE: A very interesting editorial mix-up occured with this book. In the manuscript for #50: The Ultimate, one of the new Animorphs, an Asian boy with a speech disability who was confined to a wheelchair, was named Tuan. Sometime before the manuscript became a book, Tuan's name was changed to Timmy. The manuscript for this book, however, was written before the name was changed, and Tuan ended up appearing in this book anyway. Don't be fooled -- Timmy and Tuan are the one and the same!
- ANIBASE: Captain Olston is a leader at the National Guard base where the Animorphs go to "borrow" bombs to use to blow up the Yeerk Pool. He ends up helping the Animorphs with their task, after Naomi, who was a lawyer for his son, convinces him that he should listen to Jake.
