This is a book for boys even though I am a girl and I really enjoyed reading it. Ian Whybrow got famous well-loved illustrator Tony Ross (that might ring a bell) to illustrate the book. Ian Whybrow wrote the not very well known series – Books for Boys and this one is so good I am going to try to get the others. Though this book is only sixty-four pages long every page (or nearly every page) is full of exciting events that tae place between Fries O’Mighty and Billy Humble (not forgetting Billy’s cute little dog Whizz. My recommendation is for 7 – 11 year old boys (and maybe tomboys). Rating: 7/ 10.
