The Stranger

Rachel and her friends have found a way into the Yeerk pool, but their plan to sneak in as cockroaches backfires when they realize they are on the menu for the alien Taxxons. Just as their luck runs out, a mysterious being freezes time and offers them a way out of the war entirely. The Animorphs must decide whether to keep fighting a losing battle for Earth or accept a safe haven on a distant world.
