The Unexpected
K. A. Applegate
 Someone found a piece of a Bug Fighter and the government is going to test it at a laboratory. Unsurprisingly, the Yeerks don't want it tested. The Animorphs have a battle at an airport. During the fight Cassie ends up unconscious on the belt with all the luggage. When she wakes up, she is in the cargo bay of a plane flying to Sydney, Australia. The plane is attacked by Yeerks looking for the "Andalite bandit" so she jumps out after unsuccessfully attempting to elude them on board. She hides in the sand as a flea until the Yeerks leave. After the Yeerks leave, she demorphs and meets Yami who lives nearby. He takes her to his family. His grandfather cut himself with a piece of a Bug fighter that he was using as a wood carving tool. Cassie morphs to Hork-Bajir and helps amputate his leg. Later, the Blade ship turns up again and Visser Three demands that she come outside. She does and tries to lead the Yeerks away from Yami's family. A Chee who was aboard the Blade ship turns up and she goes back home.
