 NIGHT UNBOUND is the first installment in Dianne Duvall's IMMORTAL GUARDIANS series that revolved around a female character, and although Lisette & Zach's tale was undoubtedly passionate, it didn't quite measure up to its male counterparts. Some major questions get answered with regards to the main story arc, and there's no shortage of action or romance, but I failed to connect with the protagonists which caused the love scenes to lack chemistry. After four amazing books, I have no problem with giving the author a mulligan because we're all allowed one, that's the rule! 
 Throughout this series, Duvall has been torturing readers with the origins of the IMMORTAL GUARDIANS, and finally some of my suspicions were confirmed. No big surprises on that front, but it was nice to have my hunches validated, especially the ones about Seth. Speaking of which, I did feel like this story was more about him than Lisette, albeit without the romantic aspects. I am getting a little tired of the supersoldiers plot line; the memory wipe / restore trick is getting old even though it does make sense for the author's eventual end game. I enjoyed meeting the new characters, Ethan and Aidan, and Cliff is quickly becoming one of my favourite underdogs. I also LOVED the shout out to Quebec! 
 I was looking forward to learning more about Lisette d'Alencon, one of the only female IMMORTAL GUARDIANS, because she's been a bit of a wallflower up until this point. Unfortunately, her role in this story seemed almost trivial at times, and her character wasn't developed nearly as much as I would have liked. In fact, she came off as ditzy instead of ferocious which was disappointing because it made her pale in comparison to her male team mates. Zach's another one who's been lurking in the shadows, and the author was somewhat limited as to what she could unveil without giving too much away about the Others, so I didn't mind his murkiness as much. 
 Things heated up quickly between Lisette & Zach which made NIGHT UNBOUND the hottest installment yet! The latter's telekinetic abilities sure came in handy--no more searching for the elusive g-spot with that card in your deck! However, I did feel like the numerous sex scenes were trying to compensate for this book's lack of relationship growth, and the result was steam without chemistry. I found myself not really caring whether Lisette & Zach got their HEA because their romance was somewhat eclipsed by this series' plot arc, and I just wasn't invested in their love story like I was with previous novels. 
 If you like a lot of motion in your ocean, then NIGHT UNBOUND is sure to satisfy.
