When I can I try to read the books that are proposed to my son.

A two weeks trip to the USA was a good opportunity to do so.
Ernest et Celestine is a good reading for an age between 8 and 10 years: the subject may appear light at a first glimpse (the story of a mouse and a bear) but the message about against using prejudices as the guiding criteria of relations is very strong and clear.

While the construction of the phrases is simple a few words will likely be missing in the vocabulary of a kid: be prepared to answer questions or have a dictionary for kids readily available.
