Mr Mumbles, Paperback Book
5 out of 5 (1 rating)


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.

Review by

This had me up until the wee morning transfixed on the page (ok, screen: it's only available on Kindle in the US) and I was so disappointed when all the perfect suspense and horrifically enjoyable action was done that I downloaded every other available book. I hope he gets published in the US soon so I can have hard copies. The series of Invisible Fiends is fantastic. Please note: this book is aimed at older children, but any age that likes to be scared would love this book.
