SPOILERSAcross the Great Barrier (Frontier Magic, Book 2)
by Patricia Wrede
Sequel to Thirteenth Child and, while I still really enjoyed reading this one, it was much slower than the last. I also keep forgetting Eff is supposed to be an adult but there was more adventuring so I'm happy. Lan, Eff's twin brother and a seventh son of a seventh son, is pretty insufferable and I'm not happy he's taking a more prominent role in the books. I liked it better when he was always off at school.
Also I want a pet mammoth.
I must wait until August for the next book :(
