This is part 6 of the Fever Series. Recommend reading them in order. 
 Dani O'Malley is a fourteen year old girl who is leaving in Dublin after the Wall fell. The Fae are everywhere and she is trying to kill them all. Her Sword of Light and Mack's weapon are the only two tools that can do it. She has many powers, super hearing, super speed and likes to think of herself as a super hero. 
 Ryodan is interested in Dani. He forces her to start working for him. She agrees because a friend's life is in danger. 
 Dani has many hiding places and she has some in common with Dancer. 
 Dancer is human, super smart, handsome geek a few years older than Dani. He has secrets we don't know about. 
 And to close the future romance circle we have Christian MacKeltar who is becoming an Unseelie Prince and seems to be obsessed with Dani. 
 In the middle of all this testosterone, something very dangerous is killing humans and Fae. People and places are being frozen and dying. There is a race to stop this before the world gets destroyed. 
 I gotta be honest here. I didn't like Dani in earlier books. With trepidation I started Iced and discover that I really liked the book. Ryodan is a super alpha male. KMM writes Dani in a way that you forget she is only 14. Can't wait for her to get older and see who she picks. Christian is a danger that you like to have around and Dancer he is the human boy holding secrets we need to know. 
 Why do I have to wait longer for the second book. 
 Spoiler Fangalert: I love that Ryodan bit her and now he can tell where she is at. Love the JZB cameo and can't wait for Mac's confrontation. 
 I hear a guttural sound followed by a weak sigh and look back at the bodies. 
 "I'm going to kill the kid," Barrons says faintly. 
 Ryodan makes a burbling sound like a bloody laugh. I don't think he even has the parts left to laugh with. "Get in line."
