For the second time, I'm recommending you read an author who I haven't had the time to read yet (but in my defense, several of her books are on my shelf, waiting for the Christmas vacation to be consumed). As Wikipedia says, "She is best known for her novels set in Victorian society and featuring lesbian protagonists." So, there you go.
I became aware of Sarah Waters via NPR's Barrie Hardymon. At this point, our tastes have aligned so closely that I will read anything she recommends, and she has been one of Sarah Waters' most vocal supporters in 2014. The Paying Guests was her big novel of the year, and has been included on many year-end lists (including NPR's Book Concierge, where you can read a review by Barrie herself).
