Rescue on the Oregon Trail by Kate Messner
The first book in the Ranger in Time series, Rescue on the Oregon Trail is part science fiction, part historical fiction. Ranger is a lovable and energetic golden retriever trained as a search-and-rescue dog who travels through time to join the Abbott family on their journey from Independence, Missouri to the Oregon Territory in 1850. Along the way they encounter many of the experiences common to travelers on the Oregon Trail, with no shortage of excitement and adventure. I’m a stickler for accuracy in historical writing and I don’t think Messner quite measures up, but more on that later.
If you enjoy the Magic Treehouse books you’ll be sure to enjoy Rescue on the Oregon Trail.
