Erin Hunter

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. ThunderClan's darkest hour is upon them, as Tigerstar's quest for power plunges all the Clans into the most terrible danger any cat has ever faced. In order to save his Clan and his friends, Fireheart must uncover the meaning of an ominous proclamation...

Tigerclaw is back and more dangerous than ever as the new leader of ShadowClan, but he is not the most terrifying enemy Fireheart must face as a new force sweeps through the woods.

While Jaypaw, Hollypaw, and Lionpaw struggle to understand their powers as warriors, the cats' faith in StarClan is tested yet again.

"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"--

"With RiverClan in crisis, ShadowClan and its leader Tigerstar step in to offer their help-whether RiverClan wants it or not"--

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.

For generations, four clans of wild cats have shared the forest. When their warrior code is threatened by mysterious deaths, a house cat named Rusty may turn out to be the bravest warrior of all.

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.

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.

Firestar, leader of the Thunder Clan, sets off on a harrowing journey to find a long-lost clan of cats that had been forced to leave the forest many moons ago.
