The Gate of Bones: The Magickers #4 - Andy Clark

Gate of Bones
The Magickers have brought evil and its battle with Jason, Bailey, Ting, Henry and the others to a world they hoped would be safe.
Jonnard and his mother Isabella now lead the Dark Hand and begin to stage devastating attacks on the new world, knowing there will be little reprisals as long as they have hostages. But what the Dark Hand has forgotten that is has never been just Jason or any of the young Magickers standing alone. They stand together, and together they are learning to become formidable. Jonnard has opened the maelstrom Gate of Bones to unleash evil as never before. Is Jason is prepared to make the ultimate sacrifice to close it?
