This question already has an answer here:
The book takes place in winter and starts off by following a young boy who just turned a certain age like 13 or in that range. The boy notices that as he was walking back home that crows or ravens were following him and looking at him with intelligence. As he passes each crow, it looks directly at him at caws while looking at him. The boy remarks on the strangeness but shrugs it off at first.
When the boy gets home, it is dark and there are street lights and as he is about to enter his home he feels a strange presence and turns around and some of the street lights are out and he feels someone watching him.
I don't remember much more than that in specifics. I want to say that something happens that night and the boy is rescued by a stranger who is fighting a battle with the people that were following the boy. I believe there is magic in there as well something that has to do with the seasons or night and day but i am not sure.
