Possibly the best academic book I've read thus far. Castle's prose is concise, well thought out, and utterly compelling. She has a knack of crafting clear arguments that take the reader on historical journeys through events and literature, taking complex ideas and explaining them in simple turns to make the text enjoyable and, perhaps most importantly, fun to read. The introduction explains that this was put together as a response of sorts to Freud's famous essay on the uncanny, exploring uncanny elements of history and literature in the 18th century. We begin with transgressive elements in famous 18th century novels, particularly those involving women and sexuality, before moving into studies of masquerade and carnival. The book, incredibly, becomes even better during a late chapter on Ann Radcliffe, while the following two chapters on phantasmagoria and spectrality are two of the best pieces of writing I've ever encountered: erudite, eye-opening, and capable of imparting new levels of historical understanding. The final chapter, on the famous case of two women who apparently travelled back in time to meet Marie Antoinette, is oddly personal and affecting. I borrowed an online copy of this book from my library, but it's so good that I had to get hold of a hard copy too.
