"Aza Ray is back on earth. Her boyfriend, Jason, is overjoyed. Her family is healed. She's living a normal life, or as normal as it can be if you've spent the past year dying, waking up on a sky ship, and discovering that your song can change the world. As in, not normal. Part of Aza still yearns for the clouds, no matter how much she loves the people on the ground. When Jason's paranoia over Aza's safety causes him to make a terrible mistake, Aza finds herself a fugitive in Magonia, tasked with opposing her radical, bloodthirsty, recently escaped mother, Zal Quel, and her singing partner, Dai. She must travel to the edge of the world in search of a legendary weapon, the Flock, in a journey through fire and identity that will transform her forever." Publisher's descriptions.
