I'm preparing a unit for 6th formers about gothic lit, and want to look at the relgious influences, e.g. the duality of human nature and how we strive for good, but are seduced by the bad. Do you know any good resources? i want to focus on the lit & linguistic devices of the genre, and also look at how the genre has developed over time, with how this relates to real life influences (including religious teaching). Any suggetsions to help me put together a book list, or do a little more research, gratefully accepted.
