I’m always really wary about reviews that begin with “I don’t like genre/subgenre [x]” like it’s a badge of honor. It inevitably leads to the reviewer making trite observations about what are probably quite sophisticated tropes, and winding up with a comment along the lines of “I’d have enjoyed this romance a lot if the central couple hadn’t got together at the end” or “This space opera would have been so much better if it hadn’t been set in space.”
Nevertheless, I feel I can’t really talk about Cecilia Tan’s Slow Surrender without first offering this bit of context: of all the subgenres of romance I’ve encountered, the one that appeals to me least is the one I think of as Billionaire & Human Female, books where the hero is some kind of tormented, maverick genius billionaire, and the heroine is, well, a human female, and often seems to have no distinctive features beyond this. Fifty Shades of Grey kind of typifies the subgenre for me. That said, this is entirely personal taste. There’s nothing wrong with B&HF, and, if it’s your kind of thing, then I suspect you’ve probably already read Slow Surrender. If not, you should. You’ll like it. See you later.
