Hearts break. Kingdoms shatter. Saoirse Sorkova is on the run. Accused of several murders, her siren identity compromised, even the newly crowned King Hayes can't protect her if she's caught.

Forced to travel with Carrick - once her best friend, now her greatest betrayer - she begins to unravel multiple plots that threaten the safety of her family, the livelihood of the entire kingdom, and her future with Hayes. And the more time she spends with Carrick, the harder it is to keep hating him . . . Soon, Saoirse is forced to question: what if Hayes isn't the right ruler for the kingdom? And if he's not, is she willing to betray her king - and her heart? Featuring an all Black and Brown cast, a forbidden romance, and a compulsively dark plot full of twists, this thrilling YA fantasy series is perfect for fans of A Song Below Water and To Kill a Kingdom.
