Although I'm a super-consumer of fiction, my softest spot is for children's books (thanks to running the kids' department at Waterstones). They are SO good. Picture books are my absolute favourite.
I've order a few Bruno Munari books for work but can't seem to shift them (customers are fools and buy the boring boring gruffalo instead)
One of my favourite picture book bod's is Polly Dunbar. She writes such sickeningly sweet stories with fairly traditional and completely lovely pictures. There's a recent series by her called Tilly and Friends. The elephant story is the BEST. Tilly the elephant tried to hide. argh it's so cute and lovely. buy it.
pretty much all of my recommend cards have the word lovely on them.
lovely lovely lovely
