Allis med is

Allis and Ann are best friends. But one day, Ann is killed in a road accident. Allis becomes very cold inside and doesn't want any new friends. At the same time her parents start working abroad and therefore, she has to go live with her grandparents (who are the landlord and landlady of a big house) and begin going to a new school. But at school everybody teases her, because she is odd and doesn't want to make friends with anyone. There is also another person who is teased in the class, Sigge, who is a Polish immigrant. When a bird gets hurt and Sigge takes care of it, Allis wants to help him. And after she lets Sigge into the big house where she lives, nothing becomes the same and peculiar things start to happen, both in the house and in Allis's heart.
