In the previous book, Sarren, a psychotic vampire, killed Zeke. In this book, Allie is on the hunt to seek revenge for Zeke and do it by killing Sarren. Along with her two companions, Kanin and Jackal, they go on an adventure to seek out Sarren. Along the way, they face many dangers and surprises Sarren had left for them. The road lead them to the one place they must protect at all costs, Edan.
Right after the second book, I was worried that this series was going to end badly, but it wasn't the case for this book. Julie Kagawa exceeded my expectations on this book. I was so awed at how she wraped up this series. I was on the edge of my seat while reading the Forever Song - that's how good it was. I experienced tons of emotions while reading this story. I was anxious, nervous, happy, and sad! Allie started out to be a weak character but throughout the series she became a strong and powerful character who can do anything and I loved her for that. Although I love this book, I would change one thing about it. I would make it longer than it is because there are mysteries that haven't been solved yet and I want to get more information about what happens after the story ends.
