Fantasy Romance, or "Romantasy" is a newer genre that I'm just dipping my toes into, and I'm loving what I've read so far. If you haven't already, the very popular, Sarah J. Maas's A Court Of Thorns and Roses is a good start, I think! I'm currently on the 3rd book and It's so good!!! I think ACOTAR has the "Secretly trying to protect" thing nailed down pretty good. The action and descriptions are also good, in my opinion. Give it a shot, maybe?
