A group of children at the Pre-School where I work had become interested in super heroes and this book was bought as part of a 'Super Hero' story/interest basket. It has since become a firm favourite with this group and many of the other children, all of whom are fascinated with the various powers that the super heroes possess. It is so good to have found an educational book that actually reflects the interests of children, especially boys, in the 3-5 years age group. It also gives a good 'balance' to the children's play - boisterous super hereoes can learn about letters! I wouldn't hesitate to recommend this book to both Pre-School groups and to children at home and it would certainly also be suitable for older children.
