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 a cold, harsh winter approaches, the cats from the mountains prepare to divide into several camps, requiring each cat to decide where his or her allegiances lie.

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.

"In the midst of the coldest leaf-bare any warrior can remember, the Clans have lost their connection with their warrior ancestors, and only one ShadowClan apprentice can still hear their voices--or their warning about the new shadow rising within the warrior Clans"-- Provided by publisher.

"Bookish high school student Rintaro Natsuki is about to close the secondhand bookstore he has inherited from his beloved bookworm grandfather. However, one day, a talking cat named Tiger appears and asks Rintaro to save books with him. Of course, "ask" is putting it politely -- Tiger is demanding Rintaro's help. The world is full of lonely books, left unread and unloved, and only Tiger and Rintaro can liberate them from their neglectful owners. And...

"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"-- Provided by publisher.

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 leader, Bramblestar, has been behaving erratically after losing one of his nine lives, and suspicion is quickly spreading across Clan borders. And when a strange apparition sparks unrest in SkyClan and ShadowClan, each warrior must decide where their allegiances lie--with their Clan, or the warrior code itself"-- Provided by publisher.
