As a child, Brian Jacques books were my favourite things to read, I just ploughed my way through as many as I could find! This however, I think is my favourite out of all of them.
It is essentially, a tale of the triumph of good over evil, but on top of that it's a story about love and friendship and bravery. The characters are all wonderfully endearing and when I was younger I used to think of them often, not as characters from a book but as friends. Martin the warrior in particular was a character who particular appealed to me, as I think he will to everyone who reads this book.
The brilliant thing about the Redwall books is that they are such a mixture of intriguing riddles, battles against evil forces, humour and wonderful characterisation. I can't tell you how I often I could live in Redwall Abbey and share in their feasts and fun.
I started reading the Redwall series when I was 6 or 7, but of course it will vary with how well a child reads (I was an early starter). However, no matter their age, children are sure to be completely captivated by this book and indeed by all of the Redwall series (of which there are a lot by the way, so prepare to shell out lots to satisfy your newly voracious reader). And let me tell you a secret - I'm 20 years old, and I still re-read them!
