Two typical Schooled in Magic novels, both relative short, and the plot meanders a bit without going anywhere. I fear Nuttall's a bit done with this universe. Power creep has made the heroine too big to fall.
As for these two books: they should have been one. Perhaps that would have redeemed it a bit.
Passable if you liked the earlier works, but to be frank, Emily's adventures in 'The Known World' no longer shine.
