The Stranger

Marco and Tobias have made a big discovery. A new way into the Yeerk pool - the centre of the Yeerks' power. If the Animorphs can just get in there and do some damage, the Yeerks could be in real trouble. All they have to do to get in is morph into cockroaches - if they can bear it. But they've reckoned without the Taxxons who guard the Yeerk pool. The hideous Taxxons who just love to eat cockroaches.
