Called by StarClan to fulfill a new prophecy, a group of young cats sets out on a long and dangerous journey, knowing only that trouble threatens the forest, as the adventures of the warrior clans continue. "Brambleclaw, a warrior of ThunderClan, has received an ominous new prophecy from StarClan that speaks of a mysterious danger. Now he will need the courage of the greatest warriors to save the clans"--Page 4 of cover.

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.

Fireheart, a full-fledged warrior cat, must confront questions of loyalty and identity as he faces the possibility of betrayal from within his own forest clan.

Firestar's grandchildren--Lionpaw, Hollypaw, and Jaypaw--progress in their training to become warrior cats and are drawn for different reasons to the mountains and the Tribe of Rushing Water.

Three young bears of different species--one black, one polar, and one grizzly--travel on a perilous quest to the Northern Lights, escorting a shape-shifting grizzly cub whose destiny will affect them all.

"In the midst of the coldest leaf-bare any warrior can remember, the Clans have lost their connection with their warrior ancestors, and only one ShadowClan apprentice can still hear their voices--or their warning about the new shadow rising within the warrior Clans"--

ThunderClan's darkest hour is upon them and Fireheart, the warrior cat, must protect his clan from a threat unlike any the forest has ever seen, as the time comes for prophecies to unfold and heroes to rise.

Fireheart, the warrior cat, faces many challenges in his new role of ThunderClan deputy as his apprentice, Cloudpaw, resists following the warrior code, Bluestar weakens, and Tigerclaw continues to haunt the forest seeking revenge.

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 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.
