I'm not a romance fan - but I love the novels of Anne Tyler; 'Accidental Tourist', 'Back When We Were Grownups' are good 'uns
.
Orwell's '1984' might also fit the bill of non-stereotypical romances.
Also, PG has "The Young Visiters or, Mr Salteena's Plan" a romance written by a 9-year old Daisy Ashford.
