I liked it a lot more before I thought too hard about it and made all the F1 connections. At a surface level its a fun & frothy romp with a bit of magic. Xavier and Mercy go back and forth between wanting to (and doing) boink each others brains out and then pulling away because they assume that the other doesn't want them, or they're not "good for" the other person. If there was more TALKING and EXPLAINING then they could have gotten together much sooner, but that would but out half the book.
The regent coming in at the end felt very forced and unnecessary, but I haven't liked that character in any of these shared world books so far.
Sadly once I realized more of the F1 connections those characterizations left a bad taste in my mouth. Xavier is basically a MaryStu stand-in for Lewis Hamilton, down to the hair, the piercings, and the tattoos. Being inspired by a real person is one thing, but copying that much detail feels weird. Mercy is clearly Mercedes, Hamilton's former team that he achieved so many titles with. Xavier's rival, the Dutchman, is Max Verstappen, Hamilton's (at one time) real life rival. Yeah, Max can be a hard driver who lives for racing, but I think the cauterization here of having him be a clueless lecher who's entire ship smells of rotting fish was a bit too much. And I'm presuming his ship, the Scarlet Cow, is a dig at Ferrari? Which is kind of hilarious, since in real life Hamilton moved from Mercedes to Ferrari in 2025 and is having a terrible season.
ETA: and the "Daddy" thing at the end came out of nowhere and was just WEIRD!
