For many moons, ThunderClan, ShadowClan, RiverClan, and WindClan have lived in peace in their territories around the lake. But now they must decipher a mysterious prophecy—a message that will send one young medicine cat apprentice on a quest to determine the fate of all the warrior Clans.

It is a time of peace between the warrior Clans, and all four are thriving. Then Firestar, leader of ThunderClan, discovers a terrible secret: The warrior ancestors of StarClan have lied to him. Firestar must embark on a perilous journey to right their wrong - and nothing will ever be the same again.

It has been foretold that Jayfeather, Lionblaze, and one other cat will hold the power of the stars in their paws. Now they must wait for a sign from StarClan to tell them which of their Clanmates will complete the prophecy.

For the first time, all five warrior Clans have settled into their true homes in the territory around the lake. But when a shockingly harsh leaf-bare season descends on the forest, a new darkness begins to spread - a shadow that threatens a beloved Clan leader, the cats’ connection with their ancestors in StarClan, and the very warrior code by which they live.

Long before Firestar left his kittypet home to join ThunderClan, a band of cats from the mountains set off on a dangerous journey in search of a new home....

They have always lived by the code—but only change can keep the peace. A new age is dawning on the warrior Clans. Now a new generation of warriors rises—one wrestling with the legacy of his great ancestor Firestar, one seeking to protect her troubled Clan, and one yearning to prove herself as a medicine cat—as leaders from all five Clans agree that the Warrior Code must be reformed.

For generations, four Clans of wild cats have shared the forest according to the laws laid down by their ancestors. But the warrior code is threatened, and the ThunderClan cats are in grave danger. The sinister ShadowClan grows stronger every day. Noble warriors are dying - and some deaths are more mysterious than others. In the midst of this turmoil appears an ordinary housecat named Rusty...who may turn out to be the bravest warrior of them all.

Echo, a water buffalo, is chosen by the Great Spirit to lead after a horrific accident—but can’t command the respect of any of his herd. Stride the cheetah is keeping secrets from his coalition that could get him killed for disloyalty.

Three young bears from different species - black, polar, and grizzly - are separated from their families when they are just young cubs. They find themselves brought together on a perilous journey. Fate is about to change all these bears lives forever.

For generations, the Silverback gorilla troop has lived in peaceful seclusion high above the Great Herd, adhering to one rule: “blood pools on the plains”. But when a new and terrifying evil descends on their home, every animal must venture into the unknown to prevent darkness from overtaking all they hold dear.

Isla and her brother are two young foxes living just outside the lands of the furless - humans. The life of a fox is filled with dangers, but Isla has begun to learn mysterious skills meant to help her survive. Then the unthinkable happens. Returning to her den, Isla finds it set ablaze and surrounded by strange foxes, and her family is nowhere in sight. Forced to flee, she escapes into the cold, gray world of the furless. Now Isla must navigate this bewildering and deadly terrain, all while being hunted by a ruthless enemy.

Farthing Wood is being bulldozed and a drought means the animals no longer have anywhere to live or drink. Fox, Badger, Toad, Tawny Owl, Mole and the other animals band together and leave their ancestral home and set off to move to a far-away nature reserve. Their journey is full of adventure and fraught with disasters: a fire, a storm, a treacherous river crossing and a hunt. The animals must unite in adversity and in doing so they learn about each other’s habits and limitations.

More than two hundred years into the future, human beings are an endangered species. The planet has been battered by war, its inhabitants plagued by disease and death. Few humans survived and remained unaffected. Most changed dramatically and evolved into something else entirely. Irrevocable alterations caused by chemical warfare have created a new species. North America is in ruins and has been overtaken. Humanity has fallen at the hands of mutants known as Urthmen.
