I'm looking for a romance novel with a strong female lead who isn't afraid to take matters into her own hands, perhaps even a bit feisty. Do you have any recommendations?

Based on your preference for a strong and feisty female lead, I would recommend "The Fierce Illegitimate Miss". The description highlights Yu Linglong as a low-born daughter with "fierce ambition" who is determined to rise above her circumstances. This suggests a protagonist who is proactive, independent, and likely to challenge societal norms or obstacles in her path. The tag 'Comedy' also hints that her assertiveness might be presented in an entertaining and spirited way, rather than being overly grim. Another novel that might fit your criteria, though with a different flavor, is "Young Master Qin Keeps Coveting Me After I Beat Him Up". The title itself implies a female lead who is capable of defending herself and taking decisive action, even against a 'Young Master'. Her "unconventional methods" proving surprisingly effective also points to a character who is not afraid to be bold and resourceful. Both novels seem to feature female protagonists who are not passive and are likely to drive the plot forward with their strength of character and determination.
