There is one book at the charity shop which is not in English. I do not know what language it is in. I would guess Eastern European. So I try to keep it prominently displayed in a relatively empty part of the children's book shelves, hoping someone who knows that language will see it and want it.
I had been forgetting to say, if I am at some time in a position to be doing story time for children in a library I would be rather tempted to try and get to read Spiders Are Wonderful. This would probably be unwise because parental objection, although there are worse choices I could make.
But so far my favourite title for a children's book is one which has been floating around the charity shop: Nature's Smallest Gravedigger.
