So far the only one I've found in this category is Iron Widow by Xiran Jay Zhaobut I'm desperate for more! I thought it added such an interesting additional dimension to the plot, and keeping the main focus on the main character's goals separate from romance helped make the romance much more realistic (but realism isn't the make or break quality here). Ideally sci-fi, historical, or fantasy – but feel free to change my mind if you have an amazing contemporary recommendation! If it's really well written, main plot works, but I'm hoping to filter out the Dark Harem Heavy Spice version of this plot – no hate to anyone who loves that though! Thank you!
