This book is great as an audio book. The voice actor is beyond... just beyond. (To infinity and beyond? Quite possibly.) We are back with Karou and Akiva and their increasingly difficult love story. I'm not super into love stories, but I am super into complicated relationships. And can you get more complicated than a Devil and an Angel loving each other? Probably not. In this book we dive deeper into each of the respective worlds. And I couldn't be happier. Read this book! (Actually, I should say: Listen to this book!)

A bigger, more in-depth review to come on my blog soon. I will update once it's up.
