This is better than the Jane Austen books, but it is long. Jane is a governess. She falls for the much older Rochester and is upset that he is going to get married. He offers to marry her, but this falls apart when it is found he was already married. At the end, he becomes an invalid and they are able to marry. There is a lot of detail and conversation in between, with family history and wealth all tied together.
Similar to Pride and Prejudice and Zombies, My Plain Jane takes the story of Jane Eyre and spins it on its head. Here, Charlotte Bronte and Jane Eyre both exist in the same world. A Victorian "ghostbuster" society is trying to rationalize its existence and recruite Jane Eyre to its membership. However, Jane likes her ghost friend and doesn't want to join. There are also the advances from Rochester as well as other shenanigans going on. With this and the Eyre Affair, I've now read two books in the Jane Eyre universe that have left me totally confused as to what the actual book is about. Maybe I should try to read the original. This one, however, is rollicking good fun.
