Here's what she's said on her blog post today:
After humans overcome a shocking attack by supernaturals centered in the Crescent City—the Second Battle of New Orleans—supernaturals are forced into a walled community known as the District. It’s not good—or safe—to have magic, so Claire Connolly risks everything when she uses her secret magic to protect a friend. Claire quickly learns the world is more complicated than she ever knew . . . and allies are hard to come by.
And how cool is it that it's in New Orleans?! So can't wait til I go there in May! And soooo cannot wait for this book either! Will continue to post info as Chloe does!
