This third book of the Edge Chronicles series is about Twig’s quest to find all his crew members after his sky ship was blown apart by a monster weather vortex. Twig learns that if Sanctaphrax isn’t cut free, the Mother Storm will waste its energy destroying it and it will never reach Riverise to restore the water. If the Mother Storm doesn’t reach Riverise, the whole of Undertown and all the creature in the woods will die and life wouldn’t exist. Will Twig be able to cut Sanctaphrax free? I would rate this book 4.5 stars out of 5 because I thought it was as good as the other books in the series.
