Emma Bannon, forensic sorceress in the service of the Empire, has a mission: to
protect Archibald Clare, a failed, unregistered mentath. His skills of deduction
are legendary, and her own sorcery is not inconsiderable. It doesn't help much
that they barely tolerate each other, or that Bannon's Shield, Mikal, might just
be a traitor himself. Or that the conspiracy killing registered mentaths and
sorcerers alike will just as likely kill them as seduce them into
treachery toward their Queen.
In an alternate London where illogical
magic has turned the Industrial Revolution on its head, Bannon and Clare now
face hostility, treason, cannon fire, black sorcery, and the problem of reliably
finding hansom cabs.
