With the help of a mysterious map, brothers Sam and Jimmy take two road trips simultaneously: one in the present day with their parents, visiting historic stops along the Oregon Trail, and one in the 1840s, where that very history comes to life. The Tucker kids get to experience all the dangers and wonders of the Trail just as the Oregon Company did, complete with buffalo hunts, river crossings, and encounters with real historical figures. This story is perfect for tweens and young adults with an itch for exploration, or anyone interested in the bold pioneers who braved the Oregon Trail.
