Puts the right flesh on the bones of Poe's story
Content warning mild spoilers for the whole book
I found The Fall Of The House Of Usher intriguing but ultimately frustrating, and judging by the author's note at the end of this book, so did Ursula Vernon. Her reworking does a great job of keeping the atmosphere of the original while filling it out to be much more of a satisfying story, with clearer reasons behind what happens and much more compelling characters.
I love how the narrator has so much of their own story, and it's mostly made relevant to the core story of the book. And the mystery aspect is very well done, with that tantalising sense that we as readers are just slightly ahead of Easton & Denton in figuring out what's going on and what will have to happen. I also appreciated how Roderick gets to be more of an actor in this telling rather than a pure victim, and I'm intrigued by the ambiguity of whether Madeline also is one or whether we're purely hearing from the fungus towards the end of the book. It must be tempting when writing a story that fills in so many gaps from the original to fill in every gap, and I think stopping short of doing that was a very good move.
