This book was kind of a mess, mostly because I thought the pacing was all over the place. The plot progression didn't feel linear, jumping back in time two years or a year when I'd have rather had those scenes and the conflict inherent in them (Brody trying to track Roselie's secret identity) be a bigger part of this book. Putting those scenes in the present tense would certainly have ratcheted up the chemistry and the tension in the book.
Meanwhile, the mystery Roselie is supposedly unraveling didn't make much sense to me. We don't see a lot of clues being discovered, we're just told that things have progressed. We see Brody being terrified for Roselie, but we have no real stakes or hints to the person's past behavior to discover WHY. And the entire mystery needed to get going much earlier, as it was still wrapping up two pages from the end. I mean, the ENTIRE reveal and explanation as to what they've vaguely been figuring out is sort of all dumped with about forty pages left, and it didn't have enough to do with the hints that had been dropped earlier in the book to make the payoff work for me.
This series has been so hit and miss for me; the plots tend to be the weakest parts and it hurts the characterization. Roselie is the only female spy for the home office, but we don't really do much with that. The entire book is Brody telling her she can't do things because it isn't proper or safe while she goes out, tries to do them, and gets in a scrape and he frantically tracks her down from townhouse to party to ball to wherever. And her obstinacy and his fussiness made them unlikable at times. Mostly because I didn't know much else about them.
Plus, while chemistry between characters has never been a problem in this series, I didn't feel anything for Roselie and Brody. We didn't really see them interact much unless they were mad at each other or kissing, and I honestly wish this hadn't been a trapped into marriage plot as there was too much other stuff going on. We're told they like each other and are drawn to each other so much, and they both think to themselves they love the other fairly early in the book, but there was no tug to make those feelings matter. Even his discovery of her identity was a let down, because it happens s matter-of-factly, and if it was that easy for him to notice, it makes it seem even dumber and more implausible that he hadn't already. I wanted there to be more impact from that, but that would have required more scenes of them together and a better understanding of their past.
The romance in a romance is inevitable, of course, but it also shouldn't be taken for granted. There still need to be some stakes. We didn't get enough to establish Brody and Roselie's past. I felt like at one point he said he'd screwed everything up between them, but we didn't really follow up on that. And the flashbacks to their previous kisses when Roselie was in her spy guise felt totally unnecessary, because it meant I lost some of the tension of waiting for them to kiss each other - Roselie and Brody, that is, not Brody and this enigma we're told he was chasing. I wish we'd had a prologue that established their closeness when they were younger to give us a better hint as to their personalities and opened with one of the kissing scenes and THEN proceeded to the plot.
The background characters also had potential, but they didn't feel as fully drawn as background characters in previous books in the series had been, which was too bad. And there was SO MUCH BLATANT HINTING about future couples/conflicts, but not in a way that added anything to this book. Still, the Hathaway brothers are a delight and added a lot (though I wish we'd better established their relationship with Brody so this could stand alone); I wish the dummy friend had had more to do (though I am about 99% sure he is the lord Mariah was speaking to otherwise why introduce him); and I wish we'd seen some scenes of Brody's set just hanging out and having a chat outside of the opening scene of the book. Friendships tell us a lot about characters, and that was missing in this book for me.
I don't know. This installment was the weakest so far, and suffered many of the same flaws as the third book in this series: a plot that made little sense, didn't progress in any logical fashion, and was hampered by extraneous points of view. I'll read the next one (if there is one) because I DO find Elizabeth Boyle's books charming and fun (and there were certainly some fun scenes here), and because I want to know if I'm right about Mariah's mysterious lord.
