The Next Passage — K.A. Applegate

In this middle grade “choose your own adventure” story, the reader decides what choices to make when an alien threatens to kill their character's father.

It's time for our next mission and it's up to you to decide whether you want to join us. You probably already realize that each mission -- each battle -- could mean alien infestation, or worse. You probably already realize that we win about as many as we lose. But we are managing to hold the Yeerks back, and one more person could make all the difference.

Just so you know, there are going to be a lot of decisions to make. The right answers keep us alive. The wrong ones -- well that's pretty obvious. So what do you think? Are you ready to become a weapon against the alien invasion? Are you ready to morph -- to change from an ordinary kid into an animal, a bird or insect, all in the name of saving the world?

Are you ready to be an Animorph?
