Yes, I suppose you can view this book mostly as a love story. That's what I did at age 13 - but that's why I was left disappointed back then¹.

Or you can view this as an story of formation of a strong and independent female protagonist, a nineteenth-century feminist, light-years ahead of its time. And that's what left my now-closer-to-thirty-than-twenty self very satisfied and, quite frankly, rather impressed.²
