Visser Three is still trying to find a way to reach the Pemalite ship that was hidden thousands of feet below the ocean's surface.

Jake and the other Animorphs acquire additional deep-sea morphs in order to stop the Visser's plan. But while trying...

Andalites have finally arrived on Earth. Ax and the other Animorphs now have allies willing to fight against the Yeerk invasion. But there are only four Andalites. Not nearly enough to defeat thousands of Yeerks. Not enough to stop humans from being infested. Everyone agrees that the battle must continue, but the Andalites don't want to fight alongside humans. They feel their skills will be less than adequate. And they demand that Ax choose a side....

Ax and the Animorphs have always believed Ax was the only non-infested Andalite on Earth. That he alone survived the terrible battle between his people and the Yeerks. Until now.

Rachel and the others can't let the Helmacrons stay inside Marco's...

Not only is Cassie totally alone, she's managed to find herself in Australia. In the rural Outback. The other Animorphs don't even know she's there. Cassie doesn't have any idea where she's going, or if she can even survive the rugged terrain. But she does know she has to get to a town or village and contact her family...

Ax and his friends know that Visser Two means business. There are only two ways to keep him from destroying everything...
