Absolutely wonderful! Bought for 3 wee ones of varying ages. They searched high and low for them every morning. Letters turned up in cereal boxes, in the bathroom, on the dog… some days they were easier to find than others. The stories were fab and the children loved the humour & were hooked, wanting to find out what would happen next. Have ordered for this year already, they are too good to miss! A new tradition which is loved.
