Arkie, an adopted 12-year-old girl, blind in one eye and with a tentacle-like arm, lives on an isolated peninsula with her over-protective father Blister, a giant octopus. But when an explosion echoes through the trees and Blister goes missing, Arkie enters the forest, taking the first step on an epic journey to the City of Light where her dad is being held prisoner. Arkie finds a ragtag collection of allies and foes who promise to help her on her quest, as Arkie must also face the dark truth about her origins and realize that her true power lies in her imperfect but unique self.
As her world is shrouded in darkness, a young girl must overcome her fears and travel to a mysterious city of light, save her father from a dangerous scientist and prevent the destruction of her planet.
