Originally published in 2011, this book is a story of three children's vivid make-believe battle to protect the castle from fierce dragon and terrible beasts.

The illustrater, Helen Oxenbury's work on this book is just so beautiful. Her style reminds of children's books from the 90's and 80's. Soft watercolors with relatively simple yet still intracite linework makes for a timeless look that complements the book a lot.
