The Yeerks aren't playing around anymore. They're no longer hiding behind a silent invasion. And one of the first steps in their new plan is to take over the National Guard, to prepare for all-out war against humanity. Marco and the other Animorphs couldn't be less prepared for this news. The Yeerks know who they are, forcing them to hide to protect their families. Things are falling apart, and for once Jake may not be able to make the decision that...

The battle is still raging, and it's out-and-out war. Jake and the other Animorphs have found a way to slow the Yeerks down, but now the Yeerks have decided the best way to win is to just destroy everything and everyone who gets in their way. Just when things look hopeless, Jake and the others discover help where they least expected: Taxxons. Creatures so foul and heartless, it's hard to believe that they're capable of having any feelings. But Jake...

What would you do if you had the opportunity to change your life? Not just where you live or who you hang out with, but your past, present, and future? Sounds like it might be pretty cool, right? Well, that's what Jake thought. He thought it might be easier if the Animorphs had never existed. If they'd never met Elfangor. If they all had the chance to be "normal" kids. Jake gets his wish. But things aren't quite as simple as they seem. Just because...

There is a chance for the free Hork-Bajir on Earth to start their own rebellion against the Yeerks. They have the numbers, but they don't have the weapons. They've learned from the last surviving Arn -- the race that created the Hork-Bajir -- that Aldrea, daughter of Prince Seerow, knew the location of a stolen Yeerk vessel. Unfortunately, the only way to recover the ship is to ask Aldrea herself -- and she's dead. The Arn have Aldrea's persona stored,...

Elfangor-Sirinial-Shamtul is an Andalite war prince-the one who gave the Animorphs the power to morph. "The Andalite Chronicles" is the story of how this warrior-cadet ended up on planet Earth Ages 9-12. Pub: 12/97.

We could blame everything that happened on Marco. He was the one who heard about the downed submarine. He was the one who thought we should check it out. And everyone knows that if Marco's up to a challenge, I'm definitely there. Everything was going fine. Until the explosion. An explosion that blew us millions of years back in time, to the age of dinosaurs. Now Tobias, Cassie, Marco, Ax, Jake and I are fighting for our lives with every step we...

Dak Hamee is a unique Hork-Bajir. His people call him a seer. He learns more quickly and completely than the rest of his docile race. Hork-Bajir like him are born once a generation. Aldrea is a young Andalite. Daughter of the notorious Prince Seerow. It is only after she and her family are sent to the Hork-Bajir home world that she begins to fight the Yeerks - and, with Dak's help, ultimately discovers their hideous plan. Esplin 9466 is the Yeerk...

The Yeerks have decided to try a little experiment. They've decided that if they can develop a way to make people more "willing" to be infested, they can speed up Earth's invasion. So the Yeerks try to invent a substance that will take away the human ability to make a decision. A substance that will eliminate free will. Now the Animorphs are not only faced with trying to slow down the Yeerks' invasion, but they also have to put an end to the genetic...

We never should have done it. But we needed a break. Some time off from the superhero stuff. A chance to act like normal kids. Well - as normal as four kids who can morph into animals, a boy trapped in a hawk's body, and a bright blue alien can be. Everything should have been cool. Now Rachel is missing. And there's this... this thing that's after us. But it's not up to me to tell the whole story. Tobias, Cassie, Marco, and Ax were there, too....
