Read the book that began a phenomenon—and join the legion of fans who have made Erin Hunter's Warriors series a #1 national bestseller.

For generations, four Clans of wild cats have shared the forest according to the laws laid down by their ancestors. But the warrior code has been 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.

He's ready to leave his life as a pet behind, but the forest is full of treachery and danger. Can an ordinary housecat become the warrior a troubled Clan needs?

After recovering from the dog attack she survived as an apprentice, Brightheart is once again a warrior of ThunderClan. But moons of battle and betrayal have left her with lingering suspicions about where her Clanmates' loyalties lie. So when freshkill starts going missing from camp, she fears the worst.

Alongside her mate Cloudtail, Brightheart decides to investigate without alerting the other warriors. But as she struggles to track down the culprit, she'll have to take a leap of faith—and remember what it means to be part of a Clan.

Set shortly after the events of Warriors: The Prophecies Begin, this action-packed, stand-alone adventure is perfect for longtime Erin Hunter fans and new readers alike.

Still healing from an accident that almost killed her, Tawnypelt is eager to share the message she received from StarClan about a "great peril" looming over the clans. But her vision is dismissed by her son and leader, Tigerstar, leaving Tawnypelt with no choice but to take action on her own.

Racked with guilt that he caused his father's death, Starlingpaw is determined to atone for his mistake. His chance comes when Tawnypelt warns him of a "two-faced cat" intent on destroying the clans. Believing himself uniquely suited to find this cat and stop them, Starlingpaw seizes on the opportunity to prove that he is an asset, and not a liability, to SkyClan.

Moonpaw is settling into her role as a Thunderclan apprentice, even as she continues to grapple with the voice in her head. But the more she tries to ignore the voice, the louder—and angrier—it grows.

Meanwhile, Twolegs have set their sights on the Moonpool, preventing the Clans from reaching StarClan. Will the cats find a way to reach their ancestors before all is lost?

The pandas of the Bamboo Kingdom have never forgotten the great flood that ended the peaceful life they'd always known. But for three young creatures born that day, the flood marks not an end, but a beginning—the beginning of their struggles to find a place in very different worlds.

Leaf, raised in the sparse Northern Forest, works tirelessly to help her family find bamboo to eat; Rain, hot-tempered, refuses to accept a suspicious new leader in her Southern Forest community; and Ghost, clumsy and uncoordinated, worries he'll never fit in with his hunter family in the mountains.

None of them know that the others are out there, but thanks to a mysterious tiger that's been threatening the Kingdom, they will soon find each other—and fulfill a prophecy that had been made long before they were born.

This first book of a thrilling new animal adventure series from Erin Hunter is sure to enthrall readers of her other bestselling series. Fans will love having a new universe to immerse themselves in!
