Other Worlds Than These

This is the story of Jack Sawyer, whom readers first met when he was twelve, crossing America and ';the territories' to save his mother's life, and met again in Black House, where Jack faces a child killer (among other evils). Now, Jack must stop a rampaging gang of infected teenagers from America-side, and the forces of the mysterious Gullet at the edge of Mid-World, before it destroys our world and all worlds. Jack is older now and his task is nearly impossible.
