There are days when one small decision can change the rest of your life. Jake, Rachel, Cassie, Marco, and Tobias never expected to find anything in the old abandoned construction site except crubling buildings, trash, and the occasional homeless person - but that was before they saw the strange light in the sky. Before they met a dying alien prince named Elfangof. Before the were given the power to morph into any animal they touched. Now, these five kids - the Animorphs - are Earth's only hope against a secret invaision by a race of parasitic alien slugs called the Yeerks. Can they face all the surprises that will come - and still have time to be normal kids?
