Growing up, orphaned Josephine didn't know who or what she was--just that she was "bad," an outcast with strange powers. Her baby brother, Thaddeus, was as perfect as she was flawed : protecting him became her entire life. The day he was taken away began Jo's transition from angry girl ... to would-be superhero ... to enchanting villain.
Severity reflects intensity, not value — “central theme” means a warning is a core part of the book, not that the book is bad.
