William Locke is playing with his friends and loyal dog, Spartacus, when he hears the king is waiting for him at his family's cottage. As William quickly heads home, he has no idea that because of King Herodotus's obscure vision and an ancient prophesy, he has been chosen to save the kingdom from annihilation by recovering a powerful stone with magic nobody understands. William accepts his fate with one condition-that Spartacus may join him. With their sights set on finding the Millennium Stone, the two companions venture into the treacherous kingdom full of witches, imps, undead, giants, and worse. With fate on their side, William and Spartacus meet an orphaned pickpocket, an amazing swordsman turned frog, and an incredible crystal dragon. Together, the unlikely friends must valiantly fight the mysterious darkness that threatens to consume everything. Now only time will tell if they will unearth the stone before it is too late for all of them. In this charming young-adult adventure, a boy and his brave dog embark on a journey to find a magical stone that they hope will help save their kingdom from a tragic ending.
