A Clan's future lies in a promise from the past.

Graystripe served ThunderClan for many moons before retiring to the elders' den, and was Firestar's most trusted friend and deputy. He promised Firestar that he would never abandon his home. But as new tensions strain ThunderClan, Graystripe will need to call on all of his long history, leaving ThunderClan behind in hopes of finding an answer that might save it.
