Vampire's Omega
So I don't know how this book will be for some of you guys as it is extremely dark and might be frustrating for some.
It has nonconsensual sexual intimacy, very traumatic past, extremely controlling and dominating both male leads, remember none of the male leads are hero, they both are Villains but in their own way. The female lead just have to choose the villian who she finds tolerable enough.
The male lead is a psychopath, and a monster. Remember he's not a human, so don't expect him to have emotions or human like tendency to understand his wrongdoings.
