Erin Hunter

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. Fireheart is a ThunderClan warrior cat now, but danger still lurks in the forest -- and possibly closer than he thinks. With the chill of winter setting in, the cats of rival RiverClan are growing restless, while WindClan is weak and facing threats from all sides. As tensions build to an explosive...

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.

Amidst ongoing strife within and between the Clans of warrior cats, Brambleclaw is tempted by the dark plans of his father and brother, and the meaning of Leafpool's ominous visions becomes clear.

When the bears learn of the legendary Last Great Wilderness, a fabled bear paradise, they believe that this must be their ultimate destination.

At the edge of the Endless Ice, the four bears Ujurak, Toklo, Lusa, and Kallik reach Star Island, where a large group of bears is in trouble but believes Lusa is destined to help bring back the favor of the spirits.

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.

The warrior cat Clans arrive at their new home and set about exploring and fighting over the unfamiliar territory.

"As a leaderless RiverClan faces disaster, its warriors and its young medicine cat apprentice are determined to protect their Clan and find its new leader-even if it means lying to the other Clans"--

"The Wild Dogs' fierce Alpha reluctantly agrees to let the Leashed Dogs join their pack--but after learning of Lucky's role as a spy, Alpha casts him out of their camp and orders him to never return"--

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.
