The story continues from book 2 where Nyx has been kidnapped and Sebastian's all clingy after their bond is severed which drives Nyx crazy so they're all out to try to get their weird relationship back together. We get to see a few new characters one of which is Clyde the Hellhound, love him. 
 Quite a few twists and turns I didn't see coming, I am really enjoying this series and think it keeps getting better I am definitely hooked and can't wait to see what happens next!!!
