Ax and the Animorphs have many enemies. Visser Three, the agressive Yeerk general obsessed with destroying the Andalite bandits. Visser One, the Yeerk who holds Marco's mother as a host -- and know's the Animorphs' secret. And at one time, they had to go head to head with Visser Four, the Yeerk obsessed with destroying human history in order to make the Yeerk invasion easier. Now there's a new enemy in town.
Visser Two has arrived on the scene, and he's got a plan to make the invasion of Earth easier. He's going to try and start a nuclear war between the US and China, in hopes that the war will spread and the strength of the humans will ebb. It's up to Ax and the Animorphs to stop Visser Two, trying to keep the peace by hitching a ride on an aircraft carrier. The Animorphs have had a lot of luck in the past, but this time there may be no way they can stop the world from being destroyed....
