Stormslinger — Erin Manning

Most days, Sam Oldfield seems like an ordinary kid. But it's hard to be ordinary when you're really a powerful Enchanter destined to save a magical kingdom. Other Enchanters have been using their magic for evil, and Sam may be the only one who can stop them, thanks in part to the mysterious and magical Sand Stone that only Sam can use.Some days, Sam wonders what's more important: learning to use magic to save the kingdom of Ebdyrza, or passing seventh-grade math? At least Christmas break will be normal -- or so Sam thinks, until the spell keeping Enchanters from crossing the Divide into the ordinary world is destroyed by an Enchanter Sam would rather not meet again. And when Sam and his friends must flee into Ebdyrza to escape a powerful enemy, Sam's worlds collide at last, as Sam must be prepared to fight not only an enemy, but a member of his own family.
