(Super nice cover made by Flakeshadow!) Darkness has fallen on the Clans. The tyrannical Tigerstar, with the help of the savage cats of BloodClan, has taken over the forest. United under what is now TigerClan, the ex-warriors of ShadowClan, WindClan, RiverClan and ThunderClan live as rogues, or have left to become kittypets. Meanwhile, the sun has disappeared behind a thick layer of dark gray storm clouds. A permanent leaf-bare sets in, and many cats die. A young cat, half-BloodClan and half-ShadowClan, chosen by Tigerstar as his personal medicine cat, receives a sign from StarClan that could possibly save the warrior code and its way of life. In order to save everything, however, she must find a way to take out the two most powerful cats to exist, along with their entire Clans of cold-blooded killers.
