Hi I remember reading this book, but I can't for the life of me remember what it is called, any help would be appreciated 
Its a YA book, set in London, it starts with a boy at school, a Jewish school if that helps. He then goes to secondary school and realises that he is gay. The next thing I remember is him and his friends going to a holiday let in the countryside maybe coast, and after their exams his friends mum throws a party where she's decorated all the rooms in different themes.
That is all I can remember about it, if anyone knows what this is I would be grateful as I keep thinking about it about every 6 months and I can never find it. Its getting frustrating
