I have very mixed feelings about this book. I love how Corine keeps growing and always stays loyal to her friends, even though her decisions can't always keep them safe.
As shown by this book, where she must travel to Sheol (the demon realm), after her best friend is kidnapped. She has plenty of misgivings before the journey, but she could never have foreseen all that will happen. I suspect some of the events of this book are probably going to have some extremely far-reaching consequences.
