Summary in English:

Dylan is an American boy like many others. One thing makes him special, though: his parents come from other countries and speak to him in different languages. It's his birthday today and he receives a very unusual present, only to lose it shortly after. Together with his best friend Emma, a sweet bilingual girl born to South African parents, Dylan sets out to find his lost birthday present. During their search, the two friends learn about the value of friendship, of speaking different languages, and of appreciating one's own as well as others' cultural and linguistic background.
If you are looking for a children's book that will help your child see the value in speaking other languages, in being multicultural, and that will hopefully get them excited about learning languages, this book is a great choice.
