Cornwall Map

A modern classic!
Jack Trelawny presented his book to my sons school. The story and interactive introduction inspired both my children to request signed copies. My eldest told me exactly where to go and at what time! Considering he has problems with his memory, this is no mean feat! I might also add that he is a reluctant reader and very few books capture his attention. 

  My 7 year old ASD child who cant read was also taken by the book and even though he usually throws books away in frustration, he really treasures this one. 
  I have read this book with my children and its brilliant. Not just the story which is an adventure set in Cornwall but the text, the layout of the book, the colour of the pages and the length of each chapter. These points may not seem important to some but those parents who have reluctant readers or those with dyslexia, irlen syndrome, ASD etc will appreciate how important these are. 
  If you want to buy a child a gift then make it this one!
   Note the author: Thank you!

Great Books!
My son won this book in a raffle and was absorbed from the first chapter! He then progressed to haranguing the local bookshop for the second and third books!
  They can be somewhat bloodthirsty, but this does not seem to bother children (in the tradition of Grimm etc!), and there are many good touches that make them think - the slave boat going to "Acirfa" for instance. When he worked out this was Africa, he then started looking for all the other anagrams!
  As we live in Cornwall, he has had fun spotting the place names of places we go and have been to.
Great book for reluctant readers too -  I have recommended to several friends children, who weren't that keen to read, and they have all been engrossed too!

Reviewed by boy, age 10
This is the first book I read by myself, I loved it and kept wanting to read more. I liked the descriptions of the scenery & the creatures, especially the crabs, I could picture them all in my head. I liked the maps too. The ending was good, I want the other Kernowland books for my birthday.

Reviewed by girl, age 8
I thought it was a fantastic book and I loved it. I like the fact it has a map and that it is based on real life. My favourite character was Louis because he had lots of different weapons. I especially liked the part when Louis was in Eden Valley.
