Query: Smart, Unclassifiable Ride

Reading this book was an odd experience. The historical setting was convincing, the characters strange and alive, the commentary disturbing. Sarah Canary herself is an enigma; we never discover who she is or why she's here, but those who meet her are held captive by her spell. The novel bogs down in the middle, but the end is heartbreaking and inevitable.
