Jeff Madison and the Shimmers Of Drakmere (Book 1)

What if there existed a dark kingdom forged in a web of evil spells, with a conniving king plotting to infiltrate the dreams of children all over the world? What if a king and a wicked witch could inject the sleep of every child with the most horrid of nightmares? ... All they needed was one very particular boy.
When Jeff's brother Matt is captured and spirited away to the kingdom of Drakmere, Jeff knows he must save him. But who are the mysterious, cloaked strangers on Matt's trail? And what do they mean when they say Matt is a dream catcher? Soon Jeff faces a choice: He can follow the strangers through the moonglow doorway into the perils of Drakmere or stay at home and risk the possibility of never seeing his brother alive again. And time is running out, because Jeff must make his choice before the last of the moonbeams passes and the doorway closes forever ...
