 I never planned on giving any of these books such a high rating. 
 But I LOVED this book. 
 Origin picks up where the last book left off - Katy has been taken hostage in Daedalus and the separation is ripping Daemon apart. She has been emotionally destroyed, but refuses to give up. As she navigates and learns just what Daedalus is about, Daemon calls in every favor he can to get him back to her. 
 He doesn't care if he's captured, he just needs to be reunited with her. He gets his wish in spades and with them both in human clutches, they aren't quite sure how to get out alive. 
 I think I expected this to be an entire book about separation, but it was quite the opposite. They're reunited fairly early in the book. Daemon immediately sets off to find her, going back to Luc and calling in a favor. There he finds Luc is quite the big deal, like a mob boss. The boy tells Daemon he will help him get in as long as Daemon gets one thing: LH-11. Daemon, desperate for any help, agrees without even knowing what it is and sure enough, Luc gets him in. 
 And their reunion was super sweet. Still, they're in danger and need to find a way out. Who will help them? And what is the Origin? 
 Despite all the chaos and problems and violence, they still managed to be happy just to be together. While planning their escape, they still manage to maintain their love for the other. 
 I think Armentrout is great at writing both sap and paranormal aspects. A lot of authors either only write sap well or paranormal well so her ability to mash both is one of the reasons I love her. 
 Along with all the romance, she wrote the action so well. My attention was kept the entire time. There are casualties in this book. Are they huge? No, but most YA authors fail at actually killing off the characters that matter. We are, however, introduced to a new character Archer whom I adore. The boys in this book franchise are so much fun. 
 That's what this series is: fun. I was excited to read this and when I got the cliffhanger ending (ALIENS HAVE LANDED?!) I was going crazy to get my hands on the next book. 
 Must own this series. Must get it signed. Absolute must.
