Dream Keeper Chronicles Series by Mikey Brooks, Cas Peace

Dreams: Dorothy called it Oz, Alice called it Wonderland, but Nightmares call it HOME.When an evil shifter takes over the gateway to the realm of Dreams, it falls to 14-year-olds Parker and Kaelyn to stop him. Their only hope lies with Gladamyr, the Dream Keeper, but can they trust a Nightmare to save their world?

When Parker’s mom is dreamnapped by the wicked Mab, it is up to him and Kaelyn to save her. When they return to Dreams, they discover Mab isn’t their only problem. Gladamyr has lost his powers and the only way to get them back is to become what he fears the most — a nightmare.

When Mares escapes into the world of Awake, it is left to Gladamyr and his teen bonds, Parker and Kaelyn, to stop him. They must return the most evil nightmare ever to exist back to Dreams before the barrier between the two worlds crumbles and darkness reigns forever. But to do so, Parker and Kaelyn must heal broken friendships and unite an army of children who are brave enough to conquer their fears.
