Fireheart's traitorous enemy, Tigerclaw, has been vanquished and exiled from ThunderClan - but Fireheart can't shake the feeling that he is lurking in the forest, waiting for a chance to strike. In the heat of a blazing summer, Fireheart struggles to handle sinister omens, an apprentice with a shocking secret, and a devastated Clan leader who is a shell of her former self. And as the forest gets hotter and hotter, every cat braces for the coming storm....

ShadowClan has chosen Tigerclaw as their new leader, and Fireheart fears that this old enemy still harbors dark plans for vengeance on his former Clan. A mysterious threat has invaded the forest, placing every cat's life in peril. And Fireheart's beloved leader has turned her back on their warrior ancestors. Fireheart can't help but wonder if she's right - has StarClan abandoned them forever?

The time has come for Fireheart - now Firestar, leader of ThunderClan - to face his destiny. Tigerstar's sinister ambitions have brought the whole forest to the brink of a terrible and deadly battle. Now prophecies will unfold, and heroes will rise....

Deep in the heart of the forest, four Clans of warrior cats coexist in uneasy harmony - but uncertain times are upon them, and dangers threaten the precarious balance of the forest. Fireheart is a ThunderClan warrior now, but his troubles are far from over. The cats of rival RiverClan grow restless while WindClan is weak and faces threats from all sides. Now Fireheart faces not only imminent battle but betrayal from within his own Clan.

The wild cats of the forest have lived in peace and harmony for many moons - but now, strange messages from their warrior ancestors speak of terrifying new prophecies and a mysterious danger. Brambleclaw, a warrior of ThunderClan, may be the cat with the fate of the forest in his paws. Now, he will need all the courage and strength of the greatest warriors to save the Clans.

The Clans have finally arrived in their new home, and now, they must struggle to establish territories, learn hidden dangers, and find a new place to communicate with StarClan. But more than one cat is harboring sinister plans that could lead to violence and darkness, and as the warriors wait for a sign, they begin to realize the threats they face in the forest may not be as perilous as the threats they face from within. 

Lionpaw, Hollypaw, and Jaypaw, grandchildren of the Clan leader Firestar, are thriving as ThunderClan apprentices. Yet their new responsibilities bring new dangers, and each young cat is about to discover darkness: in the past, in the Clans - and in themselves.

New territory brings new troubles for the fierce cats of the warrior Clans, and former allies are acting strangely hostile. As divisions between the Clans grow deeper, Firestar’s daughters face troubling decisions. The choices they make now could affect ThunderClan for generations to come...and with an unexpected enemy preparing to attack, their courage and strength will be needed more than ever if the Clan is to survive.

As shadows of the past continue to plague the forest, Brambleclaw is haunted by a dark figure on a dangerous quest for revenge and must struggle to remain true to his Clan. A sinister path is unfolding, and the time is coming for certain warriors to make the choices that will determine their destinies...and the destiny of all the Clans. 

Hollypaw, Jaypaw, and Lionpaw - grandchildren of the great leader Firestar - possess unusual power and talent. But secrets and uncertainty surround them, and a mysterious prophecy hints at trouble to come. The warrior code is in danger, and these three apprentices will need all of their strength to help the Clans survive.
