Okay, first thanks to Kay Pearn for this recommendation!!
This is a new-to-me Orson Scott Card series. I didn't even know it existed. And like his "Ender" books, I really liked this one. So I will definitely read the series.
On the front cover..."Come fall in love with a magical America that might have been". I know I got my daughters attention with the word magical. ha ha! But I think Harrison will like this series too, as he is the one who got me reading the Ender books.
It takes place about the time of Ben Franklin and shows an alternative America. Although Ben Franklin and the other founding fathers still existed. The main character is Alvin, who is the 7th son of a 7th son. And this apparently gives you cool magical powers.
Can't wait to read the rest!
