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. 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...
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, 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.
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.
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.
