Sasha has decided to forge a life outside of the Clans and away from Tigerstar's evil plots and plans. But life as a rogue is much harder than she expects, and Sasha soon starts to lose hope. Will she be forced to wander alone forever, scrapping for every meal and fighting with the cruel, territorial cats who dwell in the alleys of Twolegplace?
Sasha has everything she wants: kind housefolk who take care of her during the day and the freedom to explore the woods beyond Twolegplace at night. But when Sasha is forced to leave her home, she must forge a solitary new life in the forest. Life on her own is exciting at first but quickly gets lonely. When Sasha meets Tigerstar, leader of ShadowClan, she wonders whether she would be better off joining the ranks of his forest Clan. But Tigerstar has many secrets, and Sasha must decide whether she can trust him.
Sasha has returned to the forest to raise her kits, Moth, Hawk, and Tadpole, but Tigerstar still haunts her dreams. She thinks she's a safe distance from ShadowClan's prying eyes, but Sasha fears that Tigerstar will soon discover the existence of his kits. As leaf-bare stretches on and Sasha finds it harder to feed her family, she wonders if her kits might be better off as warriors, with a Clan to protect and train them. But where does Sasha belong?
