Kyle's imaginary friend from childhood is back! With a vengeance. Kyle hasn't seen Mr Mumbles in years. And there's a good reason for that: Mr Mumbles doesn't exist. But now Kyle's imaginary friend is back, and Kyle doesn't have time to worry about why. Only one thing matters: staying alive! A major series from a fresh new talent, brought to you by the publisher that put horror on the map.
