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.

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.

Moons have passed since six cats set out on a journey to save their Clans. Meanwhile, back in the forest, Firestar and Leafpaw watch ThunderClan's world crumbling around them. Will the questing cats make it back in time, or will they be too late?

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.

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.

When Firestar's grandchildren, Hollyleaf, Lionblaze, and Jayfeather, finally discover who their true parents are, there are dire consequences for ThunderClan and the Warrior Code.

For generations, four Clans of cats have shared the forest. But ThunderClan is in grave danger, and ShadowClan grows stronger every day. In the midst of this turmoil appears a house cat named Rusty ... who may turn out to be the bravest warrior of them all.

After discovering that the destiny of the Clans is in their paws, Firestar's three grandchildren face turmoil as ThunderClan is attacked, war breaks out between the Clans, and a mysterious stranger warns of more trouble ahead.

"As StarClan warns of an oncoming storm, the five warrior Clans by the lake must decide what they are willing to sacrifice to make a permanent home among them for SkyClan"--

"The Clans have finally arrived in their new home, and now they must establish territories and uncover the hidden dangers of this unfamiliar world. But the threats they faced in the forest may not be as perilous as the threats they face from within" -- Page [4] of cover.
