Thirteen-year-old Meg Murry, her little brother Charles Wallace, and their friend Calvin are guided by unearthly strangers as they go on a journey through space and time to search for Meg's and Charles' scientist father who disappeared while experimenting with a new form of space travel.

Cassie didn't pay much attention to the dreams. She and her friends have been having nightmares ever since they acquired the power to morph. But when Cassie discovers that Tobias has been having the exact same dreams about the ocean, and a voice that's calling to them for help, she decides it's time to start listening.

Morphing into killer whales, the Animorphs discover a whole new world where humans with gills exist in the deep waters below.

Rachel and her fellow Animorphs believe they have a real chance at defeating the Yeerks when they discover the location of the alien regeneration pool, but their plans are disrupted by an all-powerful Ellimist who offers them an opportunity to go live on another planet.

David, the new Animorph, at first proves to be a valuable warrior, but eyebrows are raised when he starts taking risks and breaking rules that could get the Animorphs discovered.

David, the newest Animorph, is not what he appears. His need to control the other Animorphs and Ax is all he thinks about. And the things he does are starting to break up the group.

Cassie and her Animorph companions meet a treacherous new enemy, the Helmacrons, tiny but unexpectedly lethal invaders who have the ability to shrink others to their size and who are taking hostages to recover their spaceship.

"When Earth is threatened by an invading race of bugs called the Hunger, 11-year-old Finn, his arch-nemesis, Lincoln, his crush, Julep, and one pink unicorn lunchbox become Earth's last best hope against destruction"--

Discovering that the Yeerks possess a weapon that can transform an Animorph back to a normal person with the flick of a switch, the Animorphs are forced to find a way to destroy their secret tool quickly or risk having their secret identitites exposed to all.

What's tasty, good for you, and only takes about sixty seconds to make? Oatmeal. Could this be a new weapon against the Yeerks? Will Rachel and her friends be able to return to the Yeerk pool and back to the surface without running into Visser Three?
