The format of these books is great for all young players who manage to finish them quickly. My three children follow the adventures of Tom and Lea from the beginning and take the opportunity to learn a little history. Long life to this series that sparked the desire to read with my 7 year old son (9 years old) and in many others since, as it has become my "little gift" standard for children CP / EC1 when we are invited somewhere. Recommend absolutely.
