Fresh from the exciting discovery that the beautiful kingdom and band of rebel kids she drew in her sketchbook exists in another world, Kiki Kallira has an unexpected visitor. One of those rebel kids has come into the real world to ask for her help---the river Kaveri that is Mysore's only source of water has suddenly vanished! With no water to drink or grow food, Kiki's kingdom is doomed.

Kiki returns to Mysore and quickly learns that drawing a new river doesn't work. In her search for answers, she stumbles upon the origin of the Kaveri: it's actually a princess from long ago who was transformed into water by a terrible curse! It's up to Kiki and her friends to restore the river without sacrificing the princess again---easier said than done! And with her mounting anxiety, enemies seeking to stop her, and a city growing weaker by the minute, Kiki's confidence falters. Will she be able to unravel the curse and save her kingdom before it's too late?
