Let Time Fly (Stone Shed Book 3) by John A. Heldt

In the final years of the American Revolution, Noah and Jake Maclean — time travelers from the present day — navigate war, love, and betrayal. Noah serves as George Washington's aide‑de‑camp, witnessing history up close, while Jake, a furniture apprentice in Philadelphia, wrestles with guilt over his civilian role. Pursued by relentless British spy Malachi Maine, the brothers guard a family secret that could alter the war's outcome. In LET TIME FLY, the epic conclusion of the Stone Shed trilogy, ambitions and armies collide as America and Britain march toward a final showdown at Yorktown.
