I honestly have to say I'm torn between 3 and 4 stars. It actually is a 3.5 stars and 'll leave it at 4 just because I really like the series and have a lot of faith on the main stoty it has. I love the world the author has created, I like the characters and the chemistry between them. If I love it so mucho why 3.5 stars? Easy, the story of the fight, the quest, the vessels it's really good and I think it should be the center of the book, with the romance between Mason and Jess thrown in, but I feel it went the other way round, and find it difficult to believe that two responsible people, passionate about what they do and keeping the people they love safe would get SOOO distracted with "matches" while they are in a race against Lucifer. I get it, there are times they have to wait, they love each other, nothing against sex .. seriously.. but.. people.. we have other priorities right now!! That said, I'll be reading the last book because I want to know how everything turns out, although.. we already know it will be fine, right? hehe
