Girls are girls wherever they live—and the Sisters in Time series shows that girls are girls whenever they lived, too! This new collection brings together four historical fiction books for 8-12-year-old girls: Lydia the Patriot: The Boston Massacre (covering the year 1770), Kate and the Spies: The American Revolution (1775), Betsy's River Adventure: The Journey Westward (1808), and Grace and the Bully: Drought on the Frontier (1819), American Challenge will transport readers back to the formative years of our nation, teaching important lessons of history and Christian faith. Featuring bonus educational materials such as time lines and brief biographies of key historical figures, American Challenge is ideal for anytime reading and an excellent resource for home schooling.
