Hmm...this book felt incomplete. Though Rory's post-Ripper adventures in London continue, they don't really go anywhere. Many new questions arise (source of new ghosts, strange therapist et co, relationship shifts, an injured friend) but zero zip squat resolves by the end. The Name of the Star can be read as a standalone mystery, but The Madness Underneath is firmly nestled mid-series, providing a bit more progress to the overall story but not delivering a solid plot on its own. I'll definitely be reading the third book, but I really hope we learn more about this "madness underneath" and see more of Rory's school friends.
