If you had the chance to be remembered forever, would you be willing to sacrifice everything?

If twenty-three-year-old Camilla Farrow's life were a theatrical play, she would be in the audience. But one summer night, she witnesses two young men dressed in Victorian costumes escaping down a manhole in an empty Boston alleyway at midnight. Curious and captivated, Camilla finally takes back her agency and does something she never would have done before: She follows them.

Camilla is pulled into the world of the Boston Revolutionary Art and Teacup Society, a secret society of eccentric artists and actors who live in an underground limestone fortress?an eighth Natural Wonder of the World that no one knows about but them. Enraptured by the fascinating, secluded world of the Boston Rats, Camilla eagerly leaves everything behind to start a different life under a new name: Lily.

But beneath the midnight tea parties, the theatrical performances, and the bardic battles lies something more sinister. Atticus, the leader of the Boston R.A.T.S., gives her the opportunity of a lifetime to help her achieve artistic brilliance and be remembered forever?at the cost of her inhibition, sanity, and possibly even human lives . . . including her own.

And Camilla is so entranced that she may just accept.
