Since this is a book about an assassin, I assumed it would be a fast-paced story with plenty of action and suspense. However, because of the writing style, the pacing was slowed down a lot. There were a lot of repetitious sections and many unnecessary recaps of what just happened and how the main character feels about it. There were also sections that were just verbose in a way that made it drag a bit. This included a lot of analogies and groups of adjectives that felt unnecessary. Also, the introduction was completely unneeded, as it was just an extended summary of the book. 

I think that the way women are portrayed in this book would be better suited for a male audience, and so this point may be moot if that was the intention. The book constantly gives reminders of how hot the women are. There is no nuance in this, even to the point where in one scene, a description was given where "baggy fabric" was "straining" against a woman's ample breasts. I just also would have appreciated if this woman, who is such a great professional, no-nonsense assassin, would have been portrayed as such mentally, instead of her obsessing over the men in her life - even when she has more pressing matters, like the fact that people had been trying to kill her. (Although this gets better towards the end of the book.) 

Also, from a woman's perspective, the "romance" angle was completely unbelievable. The two people in question spent only a limited amount of time together, and it was a bit awkward at that. I believe there was physical attraction, but to call it "love" was just ridiculous. What made it more unbelievable was that Delia was concurrently obsessing over how much she loved her husband. 

There were a few reveals about different people at various points. The idea of these reveals were interesting and could have been impactful if not for the execution. Especially with the second reveal about the target - this would have been a great twist if there had been more suspense and build up. (The first reveal about the target, I thought was done better.) I didn't want to see it coming, and it could have been so much better had there been more of an emotional punch of betrayal and disbelief. There were a couple of other reveals as well, at least one of which was also telegraphed a bit too much. This latter reveal also almost resolved a plot hole earlier, in which she goes home after almost getting killed, and the people who had been following her somehow don't know where she lives. But in partially explaining this, it just makes Delia look like she actually isn't as competent as an assassin as we've been told.

On a positive note, I did think Elena was interesting. She had a plan and a backstory, and I liked getting glimpses of it playing out for her. 

The latter third of the book suffered less from the pacing issues, and added a bit more excitement to the story. I think if the repetitive and over-explained bits could be edited down in favor of more character (and relationship) building, this book could be greatly improved.
