And what secret did Enrica find about Kael, don't tell me 
Spoiler!
It's how he gave up his heart as the price to bring her back to life after she killed herself with poison on the day of their 1st night. And also another condition the spell had set was that she would be afraid of him and her memories would be distorted.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
