DEMETRIUS--He's the hulking, brooding warrior even his fellow Guardians avoid. Too dark. Too damaged. And given his heritage, he knows it's best to keep everyone at arm's length. Isadora is missing. The words pound through his head like a frantic drumbeat. For her own protection, Demetrius did all he could to avoid the fragile princess, his soul mate. And now she's gone--kidnapped. To get her back, he'll have to go to the black place in his soul he's always shunned. As daemons ravage the human realm and his loyalty to the Guardians is put to the ultimate test, Demetrius realizes that Isadora is stronger than anyone thought. And finally letting her into his heart may be the only way to save them both.
