“Well, here’s the deal,” the captain says as he grabs Sunday’s face with a hand clad in delicate silk. “You come to my ship instead of your sister and, in return, I promise to let her go.”

“Excuse me?”
The captain laughs, shoving his face away.
“You seem confused, little birdie. Which part exactly did you not understand?”
Captured by the eccentric pirate captain Aventurine, Sunday finds himself trapped in a world of chaos where money holds no power, escape is uncertain and the odds are never in his favour

Summary
Eyes as golden as the sunrise stare at him in turn, from beneath furrowed brows, all pinching together in a scrutinising frown.
“What are you doing here?” He asks.
“I—” The blond begins a fumbled attempt at explaining why he’d run into this creature’s territory.
He could only croak pathetically as his trembling fingers pointed to his useless, broken ankle. Unable to run or hide, he’s forced to kowtow to the ancient monster that had smelled his fear between the raindrops.
"How unfortunate for you."
Aventurine was certainly going to get eaten.
------
Aventurine of Stratagems sincerely believes he's cursed with immortality. After another unsuccessful brush with death, he has no choice but to eke out a legendary creature known as the Owl Sage to ask about this bizarre ailment.
However, what has started as a road towards certain Death slowly becomes a story of breath-taking passion and loyalty between a beast and a man.Series

Summary
“Are you aware of the growing field of research investigating the relationship between shame and sexual preferences?”
“Amber Lord preserve us, here we go again.” Sunday watched as Aventurine rolled his eyes, huffing out a startled breath when Aventurine suddenly slumped forward, letting his forehead thud against Sunday’s chest. “How many times do I need to tell you that the only person who gets turned on by academic articles is you, doctor?”
What started out as IPC-mandated parole visits from Dr. Ratio and Aventurine turned into weekly dinners. And now, perhaps, they are turning into something more.
