To get an idea of the quality of illustration in modern children's books, check out these two non-fiction titles: Tiny, by Nicola Davies and The Book of Bees by Piotr Socha. Both tackle big, complex topics and do so with humour, sophistication and amazing graphic impact. There has been an explosion of beautiful large format children's books in recent years, perhaps driven in part by parents keen to provide their children with an alternative to small glowing screens.
