 Chained by Night takes up a couple of months after the end events in Bound by Night. Hunter is preparing for his mating to ShadowSpawn's heir Rasha, something he's not looking forward to at all. Regardless of his feelings he plans to honor the agreement. The only catch, if there is a child born between Rasha and Hunter, that first born will have to be given up to a demon as stipulated upon the creation of the first generation vampires. It is something Hunter cannot even contemplate. In order to avoid this "tradition" Hunter will have to go through and pass a series of tests that few have even tried. In order to survive the tests he'll have to place his trust in one of the ShadowSpawn twins. Hunter already knows Rasha cannot be trusted. Upon seeing Aylin for the first time he's drawn to her, but still he doesn't know how much he can trust her. 
 Aylin has always been the second born twin. It doesn't help matters that she was born disfigured. She dreams of being free from vampire politics, especially those of her father. She won't let go of her dreams. Aylin is accompanying her sister Rasha to MoonBound to attend to her before the mating ceremony. After that Aylin is supposed to be sent to NightShade to become another mate to their clan leader. It's not what she wants by any means, but she's resigned to her fate, and she keeps dreaming for better. She's attracted to Hunter the moment she sets eyes on him. Seeing that he's to be mated to her sister (who's strong and whole), Aylin knows that nothing can come of her attraction. When Aylin volunteers to accompany Hunter on his tests, it'll bring the two closer than they ever thought. 
 I thought Chained by Night better expanded the world that started in Bound by Night. I loved being immersed in just the vampire world and learning more about clan dynamics. Larissa Ione set this book up perfectly at the end of Bound by Night so there wasn't too much surprising in that regard. What was surprising was the character development, specifically with the secondary characters. We already know that Aylin has had a rough life but despite all of that she remains kind. It was more her sister Rasha that drew my attention. She's known as a cold-hearted tough warrior and she hasn't exactly been treating her twin too well all these years either. But surprisingly there are moments where we see that she does, indeed, in her own way care for Aylin. It's just been drilled into her head for so long that Aylin is deformed and is at the bottom of the totem pole, so to speak, that she's beneath Rasha's attention and I think something Rasha would get caught up with being the first born and all the attention that brought her she kind of went with the crowd. This by no means excuses her actions towards her sister, but I thought it was interesting how Larissa Ione decided to play their relationship. 
 Things between Hunter and Aylin progress as expected, but I loved it anyway. There was enough forbidden love to satisfy me. 
 Chained by Night didn't end of the cliffhanger that Bound by Night did, but there are definitely new developments that will have to be dealt with in future books. Larissa Ione also does a great job of setting up favorite characters who you want to read their story. I have a couple lined up that I would love to see get their own time in the spotlight, hopefully this comes to pass. 
 So far, with two books out, this series has been worth the read, and will more than likely be added to my auto-buy list.
