While the book has an interesting concept and the plot and world-building were intriguing, it felt a lot like a first draft. The lexicon and the syntax were less than fine, which kept me from enjoying it as I would've otherwise.
Aiden was a very likable, very complex character: he was impulsive, violent and sometimes he acted like a jerk, but, at the end of the day, he always tried to do the right thing and to protect his family.
I liked Kaia less that I did Aiden, mostly because she ran hot and cold: she was either too meek and shy or too bold and impulsive; scared of upsetting her parents or caretakers one moment and inviting a creepy stranger home the next.
Sadly, most of the other characters didn't come off nearly as complex, being either exclusively good or exclusively evil. Only Liam, Aunt Betha and Sean Mallory were interesting, and I hope they get more page space in the next books.
Kaia's relationship with Finn felt a bit insta-lovish. They did have great chemistry, but I felt they had to get to know each other better before declaring their love and be believable.
The novel had some great twists, especially towards the end and it left a lot of questions unanswered, paving the way for the next books.
