I see a lot of similarities between Clare and Emma Bovary. Obviously not the multiple adulterous liaisons, the financial extravagance and the dominating fantasy life .. but there is a certain Austenian Marianne (Sense and Sensibility) in young Emma that I also recognise in my spouse.
She, on the other hand, doth protest the comparison and points out that every girl, like Emma, wants to be a Princess.
I've been very late in getting to this novel; it's very good. They're not classics for no reason :-).
