Six months ago, Tab Bennett let go of her ordinary past and grudgingly embraced her future as an Elvish princess, born of the Light Queen and the Dark King. Queen Gwen's tragic death makes Tab the heir to the Throne of the Inbetween, but Tab's father, King Daniel, is alive and well, ruling the kingdom of the Underneath. He's made it clear he wants to meet her, and now that she knows all the heartache and loss in her life can be traced directly to the mad king, she wants to meet him too. Tab wants justice—but she'll settle for revenge, and Finnegan Blackthorn, an Elvish warrior with secrets of his own, will help her get it. Together, they'll embark on the dangerous journey to her father's kingdom. Once there, farther than ever from the Light that is her inheritance, Tab will have to confront the seductive nature of Darkness and her father's gifts.
