It used to be in my school library and was just quite a short book based around the 12 days of Christmas. The basic premise was a man wooing the girl he liked by bringing her the items from the song each day. I can't remember much more than that but remember it was a really charming little book and I would love to own a copy but can't be sure of the title and haven't come up with anything on a Google search. Will be v grateful if anyone can identify this one!
