Saudade

saudade- an emotional state of melancholic or profoundly nostalgic longing for a beloved yet absent something or someone. It is often associated with a repressed understanding that one might never encounter the object of longing ever again.

Ever since Raelynn Calirino Laumai found out that she was the long-lost princess of the European country Laumai when she was 14, she's spent the last 7 years living in the lap of luxury and fame. Life would be perfect, except... well, just a minor issue, but she's been the target of countless assassination attempts since her heritage was unveiled.
One day, she sneaks away to New York City's famously exclusive Diamond Crown Club, when she bumps into none other than her first love, Lucius Argento, who she had left behind in Maryland along with her old, quiet life.
But he isn't the same shy, sweet teenager she used to know. He's cold, dangerous, myserious, and - when did he become so hot? - but that's not the only thing that's changed.
She'll have to keep her head steady and heart safe - both figuratively and literally - if she wants to make it out of New York City alive.

Lucius Argento is the heir to the notorious Serpents, who specialize in assassinations.
His father started climbing the ranks in an infamous gang ever since he turned 15- a month after Rae, his childhood best friend and first love, mysteriously disappeared, with only a vague letter to explain. Two years later, his father started the Serpents, and it quickly became a successful mafia. one day, he's given his most dangerous mission yet by Crown Princess Beatrice Laumai- famous for her beauty and cruelty. His task? Kill the heavily guarded 2nd Princess of Laumai and make it look like an accident. But when he realizes that his target is Rae, he has to decide if he's going to follow though with it as his head and heart war with each other.
