They feel their skills will be less than adequate. And they demand that Ax choose a side. Will Ax stay with his friends... or stand with his people?

Her human name is Eva. There was a time when she had a loving husband and a son, Marco. When she had a wonderful career. But that was before she was infested by Edriss 562. Before the invasion of Earth. Now, Edriss 562 lives in Eva's head and controls her every movement. And through Eva, Edriss has become the highest-ranking general in the Yeerk empire, surpassing even her arch rival, Visser Three. She is Visser One.But it has become known that Visser One's tactics for attaining her current position were less than acceptable -- even to the Yeerks. Now she's on trial for treason. If she's found innocent she'll continue to rule. But if she's found guilty, she'll lose her life -- and possibly the life of her host, Eva. Which will mean that Marco will never, ever see his mother again...

Trying to find a way to defeat Visser Three. Trying -- like Ax and the Animorphs -- to stay alive until help finally comes.If help finally comes...

Just when she thinks life couldn’t get any weirder, she meets four ghosts who haunt the hall. They need Olivia’s help—if the hall is torn down, they’ll be stuck as ghosts forever, never able to move on. Olivia has to do the impossible for her shadowy new friends: Save the concert hall. But helping the dead has powerful consequences for the living…and soon it’s not just the concert hall that needs saving.
