Huh?

I just saw Lord of Hawkfell Island by Catherine Coulter centered in one of those book graphics and an arrow pointing at it saying Historical Rom-com.

Granted, I read this sometime in the mid 90s but, rom-com??? 

This is the one where the MMC is a Viking who takes the FMC Viking captive and his family is trying kill her?

I understand nothing about new marketing deployment of terms and how people are using/understanding them.

Any wild ones (you felt anyway) other readers have seen out there?
