I'm glad Lois McMaster Bujold 's Shards of Honor isn't in the lead, and I was wrong to give a third to its nomination. It's science-fiction, not romance, and doesn't belong on the list. Stardust by Neil Gaiman is fantasy, and likewise has no business being on the list. Both of these are simply stealth candidates whose only reason for running is to circumvent the romance category.
And that's my opinion.
