Night of soldiers and spies (ranger in time #10)

Ranger, the time-traveling golden retriever with search-and-rescue training, travels to Colonial America to help the patriot cause!

Ranger heads to the Revolutionary War just before the Battle of Trenton. He meets Isaac Pope, a fisherman turned soldier for the Continental Army. When General George Washington is in need of a spy to cross into enemy territory, Isaac is chosen for the dangerous task. Ranger must help Isaac remain safe and undetected, or the battle -- and their lives -- will be lost.
