So, this series starts off with mc finding his boyfriend and bestfriend cheating on him. He kills them. But...I forgot how but I think the boyfriend lived and his best friend died??? So the boyfriend bring both of them to this secret city where he turns the best friend into a vampire with nobility. I think.
The boyfriend was a twin, 1 gall in love w him and the other w the best friend.
Mc is the child of lilith, Adam supposed first wife who was banish...
Mc and crown prince fall in love...I think. There was also the whole wolf dad figure guy...
The ending was something along the line of best friend married to boyfriend, not the twins. They either died or I was mistaken. Have 1 boy. The boyfriend is now king, very unkind to son. And I think our mc had seggs w him cuz he found out his BFF and boyfriend for live got married while he was in an underground prison for 100 years.
I forgot how it ends but either Mc returns to his mother's side. Be with the bad guy
Remember, lilith and followers want their queen to rule edin. They starve the vampires/immortal of blood so when Mc got out of his imprisonment everyone was skull and Grey.
Or something else.

Mc got jailed cuz he was the boy from the prophecy.
