Moonblood

Desperate to regain the trust of his kingdom, Prince Lionheart reluctantly banishes his faithful servant and only friend, Rose Red. Now she is lost in the hidden realm of Arpiar, held captive by her evil goblin father, King Vahe.
Vowing to redeem himself, Lionheart plunges into the mysterious Goldstone Wood, seeking Rose Red. In strange other worlds, Lionheart must face a lyrical yet lethal tiger, a fallen unicorn, and a goblin horde on his quest to rescue the girl he betrayed.
With the Night of Moonblood fast approaching--when King Vahe seeks to wake the Dragon's sleeping children--Lionheart must discover whether or not his heart contains courage before it's too late for Rose Red...and all those he loves.
