The Quill & Key Society - Paperback

Anna-Marie and Ambrose have made a home and a new life for their ragtag family. No more scraping for food or patching over the patches time and again in their garments. All is bliss.
Or it would be if not for the explosions in the upstairs ballroom, the continuous testing of Ambrose's new abilities, and the newfound obligation they have as spies for Queen Victoria.
