Thank you Netgalley for providing this ARC in exchange for an honest review.
I happen to be a huge fan of this author and always get her books but I must say I was not a big fan of this series.
If you are reading this out of sequence it can be a bit confusing with all the characters and hybrid mixed creatures. I felt like this book tried to pack in too much and you lost the impact of the romance between IVar and Promise. Dr. Promise is a fiesty, smart woman who is powerful in her own right but IVar felt flat as a strong, Alpha lead. Disappointed.

Dr. Promise Williams is a well known physicist who studies string theory and supersymmetry. The Seven, a group of bonded brothers, need to rescue one of the team and think she has the knowledge to help them. Ivar makes it his mission to bring her into the fold because he feels responsible for his teammate being trapped. He did not expect to find Promise so intriguing. Both characters are frustrating at times and lovable most of the time. This installment is part of The Dark Protector series. While it definitely can be read as a stand alone book, it is enriched if you have read the previous books. And why would you not want to? They are all filled with worlds we only imagine, friends we long for and passion that is found in dreams. I loved Promise and Ivar. I voluntarily read and reviewed an advanced copy of this book. All thoughts and opinions are my own.

Promise is one of the top physicists in the country. Ivar is one of the Seven and has been to hell and back. He promised his brother to rescue him but he needs Promise’s brain. So he tries to kidnap her but fails. When Promise goes to try for a Grant for her university, Ivar is there. A bunch of scientists have been kidnapped and found dead and they convince Promise to let Ivar protect her. When it becomes unsafe, he takes her to demon headquarters to save her. While trying to figure how how to teleport, Ivar wants Promise to mate with him. But he soon realizes that she is his mate when the mating mark appears on him. Can Promise help him rescue his brother or will he take his place and she lose him forever?
Awesome story. Sex, demons, hybrids, and faes. Funny and a lot of big scientific words. I totally love these characters and can’t wait to see what happens next.
