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 now, but his troubles are far from over. The cats of the RiverClan are growing restless, while WindClan is weak and facing threats from all sides. Fireheart faces imminent battle-- but doesn't realize he also faces betrayal from within his own Clan. -- adapted...

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.

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.

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.

"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 warrior cat Clans have enjoyed many moons of peace and prosperity--but a dark season approaches, and those days will soon be over. Guided by a mysterious vision, the young apprentice Alderpaw of ThunderClan must go on a dangerous journey ... a journey that may be the Clans' only hope."--

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.

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

"StarClan, the Dark Forest, and all five warrior Clans band together for a final battle that seeks to destroy Bramblestar's impostor before he destroys everything they hold dear"--

Though the Clans are settled into equally divided territories, tensions are rising over the new borders, and when a group of rogue cats move in just beyond Clan boundaries, Squirrelflight is caught between her conscience and her duty to her Clan.
