My favorite: My Mr Ostrich
I guess the real aspect of this makes it more appealing, like you might run into this couple one day. A true story of perseverance. Love it.
Very flushed out, and I don't know if this kind of romance can exist in non-romance books, but it's a goal to aspire to.
I like your CEO spoils wife/spontaneous marriage/etc couples, but those are more fluff. Fun to read the face slapping, but you don't expect plot hole free stories. A fifteen point plan with no contingencies somehow always works, etc.
You know something that makes your romantic heart beat faster than my favorite? Please leave a comment. I'll try it out and update this accordingly.
