Olivia Waite is a romance author, practicing feminist, and wide-ranging dilettante.
I've lost count of how many times I've read this one. Along with Night Watch, it's one of my favorites from all of the Discworld series. It's less a parody of one specific story and more of a meditation on the definitions, limitations, and resilience of humanity. It's about history and love and death and the passage of time. It's just beautiful, and laugh-out-loud funny. Very highly recommended.
