Erin Hunter

After the warrior cat Clans settle into their new homes, the harmony they once had disappears as the clans start fighting each other, until the day their common enemy--the badger--invades their territory.

As Hollypaw, Lionpaw and Jaypaw, grandchildren of the legendary Firestar, continue their training to be warrior cats, each is haunted by a different internal struggle that could lead to trouble for all Clans.

Kallik, Lusa, Toklo, and Ujarak unite and begin their journey to discover what it means to be a bear in the wilderness, and when they gather near a remote lake to learn from their elders, they learn that one of their group is in danger, as not all bears have the best intentions.

As Jayfeather, Lionblaze, and Dovepaw continue to seek answers to the mysterious prophecy that binds them, they learn that another cat may play an essential role in defeating the Dark Forces.

The warrior cat Fireheart's determination to uncover the truth about another warrior's death leads him deep into danger, and reveals secrets that test the strength of clan loyalties.

The questing cats return to a forest devastated by the Twolegs, where they must find a way to convince their Clans to leave in search of a new home, even though they have no idea where they are going.

Bluefur, a warrior of ThunderClan, struggles under the weight of a prophecy that promises her glory as Clan leader, but also spells out her ultimate demise.

As Dovepaw, Jayfeather, and Lionblaze strive to understand and fulfill the prophecy that promises them great power, the cats of the Dark Forest begin to teach battle skills and techniques to different Clan cats through dreams.

"After an act of betrayal rocks the Bravelands, baboon Thorn must find a way to confront treachery in his own troop, while elephant Sky searches for answers and lion Fearless contends with the usurper who conquered his father's pride"--

After Alderpaw returns from the gorge that was once home to SkyClan, the ferocious cats who drove SkyClan out trace Alderpaw's path back to ShadowClan, making it their next target.
