This is one of those series that keeps getting better with each new instalment. In Origin, Katy finds herself captured by the Daedalus and all her worst nightmares come true. Even hearing about what happened to Dawson and Bethany didn't really prepare Katy for what life as captive hybrid would bring. And then there's Daemon. Nothing on Earth - or even on an alien planet - could stop him from saving the girl he loves. 
 For all those Daemon fans - I think he really shines in this one. He's arrogant, sarcastic but willing to give up everything for Katy. The snarky sarcastic conversations he has were a highlight for me. I love the way Katy and Daemon interact and I'm really rooting for this pair as a couple! 
 In many ways Origin is a turning point in the series. The first three books were mostly about the love story and the action was secondary. But now things have changed. Don't worry - there's still plenty of fluffy tenderness between the leading pair but the war between our favourite Luxens and the world... it's only just getting started. The dual point-of-view between Katy and Daemon helps bring the urgency of their situation to light. I loved getting to see how Daemon felt about Katy from his eyes and I think this is part of the reason why I'm behind them romantically. They're growing up and it's clear to see that Katy isn't the same girl she was at the start of Obsidian. She's seen the worst life has to offer but she's stronger than I ever expected. 
 I loved the action in this book. Things are happening and they're happening FAST! Some brilliant new characters are introduced (I want to know more about Archer!) and some old ones reappear. There's a cameo appearance of Hunter and Serena from Obsession (JLA's adult paranormal romance novel that's set in the same universe as the Lux novel). Armentrout isn't afraid to put her characters though hell and I respect her for that. 
 For all the fans who have been eagerly anticipating Origin since the cliff-hanger at the end of Opal - I think you'll be satisfied and impressed with how things unfold in Origin. This book is exciting, cheeky and romantic. My favourite from this series by far.
