"There are other Clans besides us?"
Life is fine in isolated, peaceful MinnowClan. But when a patrol comes back with mortal injuries after venturing into unknown territory, tales fly out of their mouths about a spiritual leader who attacked them, who hunted Twoleg's puppies as prey, who claimed to be the personified incarnate of the Moonpool, hedging between StarClan and real life, who had no eyes in his skull.
Messenger Cat Jetclaw is terrified, yet skeptical of these claims, and seeks the truth with his friends, going into the exact, fabled place the patrol went. He comes across an entire other Clan, CloverClan, with the exact leader that he was told about. Jetclaw now needs help from his friends to find a way to befriend them- or die trying.
(A/N: Changed the medicine cat's name from Duskystep to Rockytail after looking up the definition and seeing that "Dusky" doesn't fit his description, and it's a word that used to be a little racist, so...I changed it because yikes. Comment if I am misinterpreting the definition or something. I will listen.)
