Bound by Duty is the second book in the Born in Blood Mafia Chronicles and the story is about Valentina, Aria's cousin and the Chicago Outfit's new mafia boss, Dante Cavallaro. 
 Valentina is a widow. Her husband Antonio was murdered. They have been married for years just to conceal his true sexuality from the mafia world and the relationship they have is nothing more than friends. As for Dante, since his wife passed away due to a chronic illness, he becomes more emotionless and colder (Total iceberg despite he's raised by his father to be stoic and cold ). Marrying Valentina is just a duty to produce a heir and he isn't interested to get to know her. 
 However, Valentina is sexually inexperienced and being ignored by her new husband frustrates her. So, she'll do anything to gain his trust and attention and hopefully make him care about her. 
 I slightly like this better than the first book. Valentina is a lovely and brilliant heroine. She's beautiful, patient, understanding and independent. The slow burn sexual tension she and Dante have.. Oh my god. It took Dante a while to loosen up and his coldness frustrated me. Damn it but I love him and I just wish he said (view spoiler)["I love you" to Valentina. I guess Dante is too broken to say it and I feel like Val doesn't have a place in his heart. It hurts and I think she deserves more than that. (hide spoiler)] I seriously want more of these two. I WANT MORE DANTE. 
 I'm gonna grab a popcorn because it's Matteo and Gianna's story. It's going to be an intense ride. Overall, this is 4.5 / 5 stars
