The award-winning middle-grade survival series returns with its 20th adventure.

In a time when freedom was just a dream, fifteen-year-old Gabe and his sister Emma are swept into the war that would change America forever.

It's winter in New England and snow is falling on the American colonists. In a rustic cabin in the woods, Gabe and his sister Emma are left to fend for themselves when their father, a Son of Liberty, is arrested during the Boston Tea Party. After the British Army burns down their farm, the two siblings are swept into a journey that begins with Paul Revere’s midnight ride and leads straight to the battlefields of Lexington and Concord where Minutemen and Redcoats fire the first shots of the Revolutionary War. All the while, they search for their father and dream of a better future where America is free.
