Mariana Zapata...wow. This person can write. 
 Most importantly, she can write and I have no serious urge to throw a lampshade at the wall (which I used to do a lot as a kid...anger issues^^) 
 Her characters have serious hang-ups. 
 They say they will let stuff go, but a gazillion chapters later, they still bring it up. Normally stuff like that bother me in literature, but what she created was LIFELIKE characters. If you ever record what people say, and listen to it back, you'd find out we're a mess. We repeat stuff a gazillion times. We stop, and um, and aahh a lot. Conversations will happen that have no meaning. 
 I'm not saying all the above happens in this book, but what I'm saying, is when a character says she'd let stuff go, but doesn't, I could relate to it. Relate to her banging on and on about it. Because I got her. I got her issues. I got why she's the way she is. She has the right mixture of issues, for me to like her a hell of a damn lot and not be throwing lampshades at the wall for reading about characters like her. 
 Dex is a masterclass of how possessive leads should be written. I got him too. I am actually really looking forward to reading Kulti (another standalone book by this author). Yaaaay :)
