I liked Across the Great Barrier (New York: Scholastic Press, 2011) better than Thirteenth Child, the first book in Patricia C. Wrede‘s Frontier Magic series, probably because the second book doesn’t try to cover so much time in Eff’s life.
The books remind me of Orson Scott Card‘s Tales of Alvin Maker, particularly Seventh Son. Wrede’s series is better, at least so far. It’s certainly more original. Card drew a lot on LDS history for his book.
