Newbery Medalist Avi channels the mood, language, and danger of the Revolutionary War in this seamless blend of history and fiction, set in British-occupied New York City. Twelve-year-old Sophia Calderwood idolizes her older brother, William, a fervent Patriot soldier who has gone missing after the Battle of Brooklyn. In the first half of the book, Sophia’s desperate search for William leads her to several deplorable prisons where rebels are being held. The second half takes place when Sophia, now 15, becomes a spy who uncovers the truth about Benedict Arnold. The book is chockful of fascinating historical details, including the conditions for those stranded in New York and the failed meetings between Arnold and John André, his (real-life) British contact. Avi doesn’t sugarcoat the brutal realities of war as Sophia races to find help intercepting John André, who was also a boarder in her home years earlier and her first crush, in this rich, nail-biting thriller.
