Exhilarating dark romance

I usually don't read a lot of Dark Romance books, but if Rachel writes it I'll read it hahaha This is not a big book and it reads really easy and I finished it in like 3 evenings. In the book we follow Elara who is married to Rick and they have a son together. But their marriage is stuck in a rut, they barely show any affection, and she almost feels like a nanny. She works as a realtor in a firm and one day a new colleague called Ethan arrives. He is very attractive and mysterious. He doesn't talk much about himself or his past. Elara and Ethan have to work together on projects, and Ethan keeps hinting that he finds her very attractive. And he gives her the attention that she is missing in her marriage. When the line is crossed there is pretty much no way back. Will Elara figure out who Ethan is? Will she be able to keep the affair a secret from Rick? And what happens when the past gets caught up with the present? Read it now in this exhilarating dark romance, with lots of spice, questionable decisions, but somehow you will also root for the people you would probably condemn in real life. I'm very impressed by the way Rachel really makes you think about these conflicting feelings, between the choices you make with either your head or your heart.
