I personally think if you are writing books aimed at children that adults would enjoy too, you are a pretty perfect writer.
My mum was and still is a huge Roald Dahl fan and I have enjoyed all the books I have read by him.
The Witches my favourite
Beatrix Potter is very popular over here in the U.K. I love some of her books and others I found quite boring.
Terry Deary I absolutely love, as I have mentioned before. I loved history at school and I wish we got to read his books whilst there.
I am not a fan of YA books, however I wouldn't rule them out altogether. If I did I would never have read The Fault In Our Stars.
Which could be a runner up for my favourite read of the year so far.
