Y'all already see the similarities between this and "Red, White & Royal Blue". I know. I saw them too. Don't worry, all the similarities are superficial. But, to be clear, the reason I didn't like this book isn't because it wasn't RWRB. It's because I found it unfunny, hard to read (both because of the way it was written and because of how little I enjoyed the plot), and dare I say, a little too cringy for my taste. It gave very tumblr, archiveofourown levels of dialogue and inner monologue.
This book was not for me, unfortunately. For one, I did not like the writing style. It was frequently over descriptive. The main character uses oddly specific similies that I guess were supposed to be a running joke, but that I didn't find funny. Sentences went on and on to the point that I frequently had to restart passages because I lost the thread of the paragraph.
Moreover, none of the characters acted like real people. They talk in ways that no real people do, and they're all way too willing to share personal information or deep emotional truths with people they've just met.
And the actual plot was meh. The main character was so neurotic, and blew everything way out of proportion; again, I think this was partially in service of comedy, but I didn't find it funny. The chemistry of the main couple was more told than shown, and their "romance" is way too quick, even for a whirlwind romance. They almost kiss during their first encounter, and they're inviting each other to meet the family after date two? I won't drop any spoilers for specific events, but their entire relationship remains like this throughout the book. I audibly said, "What?!" out loud multiple times while reading of their relationship progression.
All in all, I found this poorly written, and surprisingly childish for a story with this much sex. I felt entirely too much second hand embarrassment reading this. There is little to no emotional depth despite attempting to explore Carter's sense of self worth and Edgar's "trust issues"; he didn't seem to have many issues with trust when he decided to track down and date a random man he'd talked to for 10 minutes max. The characters range from interesting (Carter's sister and aunt), to forgetable, to caricatures (all of Carter's roommates, the Queen of England). It honestly gave me the vibes of any given generic fanfiction on ao3. Don't get me wrong, I've read good fanfic, but this is not it.
I've heard that the author is a playwright, and that his other stuff is good, so I'll check that out. But honestly? If you're looking for a gay romance with an uppity British dude, just read "Boyfriend Material" by Alexis Hall.
