Waistcoats & weaponry

It's one thing to waltz properly. It's quite another to waltz properly with a bladed fan stitched into one's corset. Sophronia continues finishing school in style - with a range of deadly defences secreted in the folds of her ball gown, of course.

Her fashionable choice of weapons comes in handy when Sophronia, her best friend Dimity, sweet sootie Soap and the charming Lord Felix Mersey hijack a suspiciously empty train to return their chum Sidheag to her werewolf pack in Scotland.

But when Sophronia discovers they are being trailed by a dirigible of Picklemen and flywaymen, she unearths a plot that threatens to throw all of London into chaos.

With her friends in mortal danger, Sophronia must sacrifice what she holds most dear - her freedom.

Gather your poison, your steel-tipped quill, and the rest of your school supplies and join Mademoiselle Geraldine's proper young killing machines in the third rousing instalment of the New York Times bestselling Finishing School series.
