4.5 stars 
 This was precisely what I was in the mood for! Fast paced, intense fight scenes, just enough romance to keep my heart aching; exactly what I would have expected from Julie! She doesn't hold back for even an instant. I'll do my best to keep this review spoiler-free for the series, although, it will be almost impossible for me to keep some of these details to myself!! The synopsis for the book actually reveals a fair bit, so I think I'm in the clear. 
 I started this series by reading the first two books, back to back, over a year ago. When so much time has passed between books, I was really worried about how I would handle my poor memory. I tend to forget the small details... and even the huge plot twists over a year's time. Book 2 left off with a huge cliffhanger, and I had even forgotten that! Lucky for me, Julie Kagawa did the best possible job at giving a recap of the previous books, at all the perfect moments. She was able to fill in all my memory gaps without making it feel like a huge lump of rehash. 
 The Forever Song starts off jumping straight into the fray! There is no shortage of tense fight scenes, where Allison is in life-threatening peril (if she were alive, you know what I mean). She and her companions, Kanin and Jackal, are on a mission for revenge. And to save the world, of course. Kanin remains a steady moral compass for Allie, while Jackal voices all of her innermost urges. This journey isn't just a physical one, but an emotional and mental one. Allison has to make a lot of decisions about herself and how she will handle Zeke's death. This story brought me a lot closer to Allison than I felt in the first two books. It made is a lot easier to root for her. This internal struggle was missing in the Eternity Cure for me, so I was really glad to see that her decisions were not so easy to make. 
 The secondary characters are really what made this book for me. Sure, Allie was great, and she can kick some serious ass... but it's Jackal who steals my heart! He is snarky and bitter, and a perfect foil for Kanin's unshakable morality. And Sarren? He really is a perfect villain, even when we didn't actually see him for most of the book. The mere thought of him was enough to induce shivers! A villain I love to hate. <3 
 Vampires are just vampires, right? Scary in their own right, but I think we're all getting desensitized to them. Well, Julie doesn't stop at this classic horror figure. In the first book, there were Rabids. In the second, we were introduced to the Bleeders. When I started the third book, I kept waiting for the other shoe to drop. How could she possibly make things more terrifying?! I shouldn't have asked. It's a good thing this was the end of the series! I don't think I could handle the next level of horror. ;) 
 Bravo, Julie Kagawa. Bravo.
