This book was a bit of a letdown. I bought it before reading the first two books in the series and actually kind of forgot about it (I have a LOT of books on my Kindle, LOL). First, I want to say that I appreciate finding a new, young author who has a solid grasp on editing and/or a good editor. This book is not hindered by spelling and grammar mistakes that are pretty rampant these days. I also think she does a decent job of establishing setting and character, and writes dialog that isn't super anachronistic or redundant.
However, I thought the characters in the first two books were more compelling and had more at stake in their relationships. The H of the first book was physically and emotionally scarred by his abusive father, and the second book featured an H who was a by-blow struggling to learn more about his family, while that h was trying to forge a name for herself as an inventor. This H hasn't had much struggle in his life; his dad wasn't a great guy but there was nothing traumatic that happened to him. H is basically always up for a good time, likes to drink and sleep around, and over the years has really never thought of others that much.
The h, on the other hand, is a good girl who enjoys puzzles and has aspired to be published. She is on the cusp of being on the shelf and wants to please her parents by marrying, hence she makes an agreement with H. She will help him deal with the books for the ducal estate he's just inherited, and help with his sister's Season, while he will pretend to be engaged to her. They were best friends growing up, then had a falling out, but she is convinced a fake engagement is the best way to assuage her family. The author could have created tension here, but h's parents are both nice people who trust the H to a rather odd degree, considering his reputation, and he never behaves in an untoward manner.
The bottom line is, there is no real villain and neither the H nor the h learn a lesson about their lives or themselves. The book starts with a lot of silliness involving possible suitors who are invited by h's parents to attend a house party in honor of her birthday, and I wondered if they wanted h to feel a bit pressured to marry H, considering the jerks and dullards they invited. Seriously, did the dad not vet these guys? They should have been told to leave as soon as they started making bets regarding h. Anyway, they're eventually gone, and h comes up with the idea for the fake engagement. Somehow they're going to make it look real until her parents go to Greece, then in a few days/weeks call it all off, and not disturb her parents enough to make them want to come back and check on her (really it makes no sense).
I wanted the h to have a serious discussion with H about her expectations in the relationship, since he'd broken her heart. In fact, I started wondering if she wasn't angrier at him more for causing her to get rattled just before her big 18th birthday party speech than having a fling with a widow. In reality, he'd never committed to her and always treated her like a little sister. So, in a nutshell, she's chosen to turn down guy after guy over 5 years, while putting her parents to a lot of expense, because she became fixated on someone who hadn't promised anything when she was 18. Since he's gained a bad reputation but her parents don't seem to care, she should have spoken with him years before and leveled with him, if she wanted him to see her as an adult.
More critiquing below, but there are also possible spoilers...
--When H/h track down the man who's been draining the H's family coffers, the h endangers herself, bordering on TSTL territory (why must all of these h's who are supposedly so logical and intelligent refuse to listen to others in dangerous situations?). Fortunately the scene is brief. The problem is, there is no real sense of angst. The H has been earning enough money from his gambling den and investments that the money loss isn't a big deal for him. He feels guilty about his father's behavior, and his own, and he worries over h getting hurt, but it all seems a bit weak.
Also, one bad habit this author seems to have is the "h tripping scene." In this book, h is completely silly, ignores H's advice, and falls off a ladder. Straight into H's arms, of course. But can we have the steamy scene without the h being foolish?
--At the beginning of the book it's hinted that H might have suffer from a learning disability, which forces him to read slowly, and math is not his strong suit. This is the main reason for his enlisting h's help. But when he doesn't agree immediately to the fake engagement, she threatens to leave (seems pretty selfish of her, honestly), saying that he's able to do the work on his own. This subplot is then completely dropped.
--Next, where's the tension involving h getting her book published on her own? It's emphasized that this is something she wants to do to to assert her independence, but when she suspects the H may have had a hand in helping her get published, that subplot is dropped until the prologue, after they're married. It's brought up in more of a teasing fashion then. Once they've already been intimate a couple times, her concern seems to shift to being afraid he still might leave her. There's a back and forth where the H says he loves her, but she can't commit, and he tells her he'll wait for her...but not forever. What does that mean??
--The leads to the biggest disappointment of the story for me: the HEA. The h leaves a ball for H's townhouse, which is right across the street. Apparently, three weeks was a bit too long for him to wait, because he's back to his partying and impulsive behavior, getting tanked on bad booze and letting other goad him into walking on his balcony balustrade. You really, really have to wonder why this guy's friends all seem to want to watch him get hurt or mortally wounded. Anyway, this is the point in the story when H should be trying to prove himself to h, showing that he's grown up. The h should have chewed him out for risking his neck, thrown everyone out of his townhouse, and tossed out the hooch. Instead, she yells out a marriage proposal at him, and he insists in jumping down from the balcony (somehow not hurting himself) and slurs a proposal to her.
How does the H change? I'm not convinced he does. How does the h gain trust in him? I'm not convinced she does.
This is a perfectly readable book, just not as good as the first two in the series. The plot is too contrived and the characters won't linger in my imagination. The sex scenes were nicely steamy, so no issue there (they might be the best aspect of the book). So read accordingly.
