The Fourth Squire

The forest clans of the warrior cats are faced with a new disaster - a drought that leads to the drying up of the stream and the lake, as well as the disappearance of game. A young apprentice named Bluebird, possessing extraordinary abilities, learns that the cause of the water shortage is not only the heat but also mysterious brown creatures that have blocked the river upstream. A squad consisting of cats from all four clans sets off on a dangerous and difficult journey to bring water back to the lake. However, they have no idea what they will have to face. Meanwhile, the ThunderClan healer Sparrow receives a mysterious message foretelling great troubles for all clans.
