The Magickers Series by Emily Drake

A long time ago, two great sorcerers fought a duel to determine the fate of the world. Magic itself was ripped from our world, its power kept secret by a handful of enchanters. The world of Magicks, however, still exists-and whoever controls the Gates controls both worlds. In The Magickers... Enter Jason Adrian and his friends-who have been recruited by Gavan Rainwater into the most unusual summer camp on earth-Camp Ravenwyng. There, they will learn about their own special talents... moreA long time ago, two great sorcerers fought a duel to determine the fate of the world.

In The Magickers... Enter Jason Adrian and his friends-who have been recruited by Gavan Rainwater into the most unusual summer camp on earth-Camp Ravenwyng. There, they will learn about their own special talents. They'll develop their magick powers and unlock the secrets of controlling them. To Jason, it seems like a dream come true. But there is one thing he will have to do before he leaves this very special camp: face the evil minions of the Dark Hand... less

Jason Adrian and his friends survived Magic Camp. But can they survive the beastly minions of the Dark Hand. . .who seem to have followed them home?

Long ago, a war was fought between two opposing groups of magic practitioners-the Magickers, who believed in using magic for the general good, and the Dark Hand, who felt that magic belonged to them and should only be used for their own benefit. Now the Magickers are looking for young recruits to their cause-for the final battle will soon begin...

As the Magickers seek the third and most important Gate into the magic-filled land of Haven, the elder members are being stricken by a strange ailment that drains their power and ages them. And the Dark Hand is more than willing to take advantage of the Magickers' weakness to strike...

The Magickers have gained permanent access to the realm of Haven. But the forces of the Dark Hand are about to release a maelstrom of evil energy that could destroy not only the Magickers, but all of Haven.
