The ending is completely different. I read some spoilers and here some info.
My first question was about eddie. If he really killed the Leo or not. It seems like he wasn t because in the novel he was a curuel King who uses his subjects as stepping stone and a person he lusts after his brother. During the peace talks he assumes that ray is son of Leo, and says it was the duke killed his father. The happened to stay for a bit and ray meets Evan, a guy who changes his apperance. Actually he has blue eyes and he is blonde and eddie use him for s*x. Most of the people of him was aware of it.
And after his that eddie becomes more curuel with people, and restless with headaches and insomnia. I guess they change it because imply of in*est etc.
The whole family are f*ked up (●'◡'●)ノ like her Sister runs away with a gypsy who is a duke who can k*l anybody or her Husband would k*ll himself- and who is actually a king and i am not even talking about father emrassingly naive
