I read this across two flights to Tenerife and back for a golfing weekend (much to the annoyance of my 11-year-old son who was at the semi-final stage of the book) and flew through it, genuinely laughing out loud on several occasions (much to the annoyance of other passengers).
It has a feel of Roald Dahl to it in terms of its tone and humour, and grabs you from the off, with the characters introduced in an engaging way.
I'm now reading it with my nine-year-old son, who is loving the llamas and their characteristics, and we're romping through it as the chapters fly by with good pace.
I've given this a five-star review and think it's a good read for all football fans - of all ages.
