And with nomad delegations arriving for a royal tour, everything is only growing more complicated. As the threat from both the raiders and the fallen kingdom grows, Cadence and Zeke's charade is stretched to breaking point as they fight for their friends. But how can Cadence keep everyone safe when she's growing less and less sure who she can trust? Separated from her sister, Airlie has never felt more helpless. As she uncovers more about their heritage, her fear for Cadence grows. Cadence is ignorant of the danger lurking inside her, but Airlie can do nothing to warn her. Desperately searching for a way to help Cadence from afar, Airlie must find a way to unleash her own power before it's too late for both of them.
