Medicine cat Alderheart watches his world collapse as Darktail's band of rogues overruns ShadowClan territory. The ruthless leader has not only claimed their land but turned many young ShadowClan warriors against their own Clan. Rowanstar flees with his remaining loyal cats to seek shelter in ThunderClan camp. The four Clans that once stood united now splinter apart. RiverClan nurses severe wounds while WindClan seals its borders completely. Alderheart grows more convinced that finding the lost SkyClan holds the key to their survival. The ancient prophecy from StarClan weighs heavily on his mind as Darktail's brutal control spreads. Time runs short as the rogue leader's merciless campaign threatens to destroy every Clan. Alderheart must help locate SkyClan before Darktail eliminates the warrior code forever.
