Kid Beowulf and the blood-bound oath

Discover the extraordinary origin of twin brothers Beowulf and Grendel. The heroes' destiny is tied to the past, as a prince named Hrothgar begins a quest for power--one that leads him to a fiery dragon, an enchanted sword, and an oath sworn in blood. But when Hrothgar breaks his oath he breaks his kingdom, and the only thing that will save it is a family he's forgotten and heroes not yet born.
