Erik of het klein insectenboek

Erik is a curious and dreamy 10 year old boy, who isolated himself after the death of his father. He tries to avoid a class speech, but the teacher moves it to the following day. When he has to name a subject, he quickly replies with insects.
That night he stays over at his grandfather's, who will try to help him. His grandfather has a big painting in the attic with a picture of the insect world on it.
When Erik needs to go to bed, he hasn't even started to prepare his speech, the only thing he has are some drawings of insects, he made that afternoon.
