I had to buy this book…
…because it had this in it.
How I love a book with a map at the front. (Especially if the map has a little dotted line you know you will be following during the journey of the narrative. Every so often you have to turn back to the map and check where you’ve got to on that path, and what might be coming next.)
Or a family tree.
Or the floor-plan of a house – because you just know you are going to need it!
These lovely things are certainly not restricted just to children’s books. The Suspicions of Mr Whicher by Kate Summerscale has all three!
