The only love story in the novel
Dracula is between Jonathan Harker and Mina. Of course, movies have bastardised that time and again over the year, but in the book, well, old Drac isn't exactly what you'd call
cuddly...
I agree with Colin about
Frankenstein. The Baron is a much more fascinating character, driven by an obsession to conquer death, than the monster - who in all fairness is a bit of a sap and only wants a little bit of lurrrveee...
I suppose a whole host of detective novels are character driven too, from Marlow to Holmes. As Naomi says, you could put them in almost any story and they'd be recognisable.
