"The warrior code now allows a cat to formally change Clans, but ShadowClan's newest arrival feels increasingly unwelcome--and though ShadowClan warrior Sunbeam thinks every cat deserves a chance, one of the loudest voices of opposition is her own mother.Meanwhile medicine cat apprentice Frostpaw scrambles to help RiverClan stay afloat under the watchful eye of a second Tigerstar, and the shadow of growing conflict looms over them all..."--

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.

The questing cats return to a forest devastated by the Twolegs, where they must find a way to convince their Clans to leave in search of a new home, even though they have no idea where they are going.

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.

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.

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.

Amidst ongoing strife within and between the Clans of warrior cats, Brambleclaw is tempted by the dark plans of his father and brother, and the meaning of Leafpool's ominous visions becomes clear.

"It was 1798 when the Morningstarr twins arrived in New York with a vision for a magnificent city: towering skyscrapers, dazzling machines, and winding train lines, all running on technology no one had ever seen before. Fifty-seven years later, the enigmatic architects disappeared, leaving behind for the people of New York the Old York Cipher -- a puzzle laid into the shining city they constructed, at the end of which was promised a treasure beyond...

"The pleasures of the novel go far beyond the crackling, breathless plot and the satisfaction of watching the puzzle fall into place. The book is shot through with humor, both laugh-out-loud and subtle." —New York Times Book Review
