Notes

When Peter answers an ad promising to release the hidden power of the mind, he doesn't expect to find anything as squalid as the entrance to Dr Black's office. The mysterious doctor isn't quite what he seems, either. But Peter is so determined to change his life that he ignores the warning signs ... and then it's too late. Powerless to escape an experiment that goes horribly wrong, Peter faces a life-and-death struggle with an invader in his mind.
