The grammar and writing skills are very clunky but that will come with experience - the main thing is the story is OK and makes us want to know what's going to happen.
Frankly I think the Dursleys have lost their marbles if they think they can get away with this. Unless Voldemort is controlling them they sound OOC and OTT!
Thanks for the review. I hope the grammar and writing are okay and that they will improve, i'm not too sure what I am do about them right now. I am glad you think the story is OK.
In all honesty I can't really remember the staring chapters too well a it was such a long time ago and a lot has happened since then. I will definitely look back over them and possibly edit them a bit though it will have to be when I have finished writing the next chapter.
Thanks for the criticism I do value it, keep reading and let me know what you think.
