4 possibly 4.25 stars. I just finished it so I'm not sure yet. 
 I'm going to try to write something coherent, bear with me. 
 I really enjoyed the story and the world. No, it wasn't that original, we have a common trope : (view spoiler)[the lost princess (hide spoiler)], but I didn't mind that much since it was done pretty well. 
 When I bought this book, I thought it was YA (my bad really, since it's written Adult on GoodReads). Just so you know it's not, just like A Court of Mist and Fury is not YA. I personally don't mind but if it's something that you don't like, just know that the main character is 23 and the love interest is around 33. Plus there is few explicit sex scenes. 
 Which leads me to the thing I like the least: the alpha-male. The love interest, Griffin, was not that bad. In fact I quite liked him. Except when he said things like : "you're mine", "I claim you" (for this one, it's supposed to be something specific to his kind but still, it's not cute)... 
 However I really like Cat and how she handle things. She's pretty strong (she is the kingmaker after all.) 
 I also really like how the author handle the whole abduction thing. At the beginning of the book, some of the characters keeps telling our main character, Cat that she needs to accept her new situation, after all she is being fed and they are being nice (I know, yikes) But she always answered things like :"hmm no, you basically abducted me, so no I won't accept???" which was the perfect answer and I really appreciate that. 
 Like I said, the world was great, and with greek mythology, how can I not? Overall, a strong fantasy romance.
