Azazel - Lucifer's Son

Jolie Vlada has always lived in the white spaces at the margins of other people's stories, invisible and quiet, convinced her life did not carry enough weight to leave a mark. Raised in Sighișoara beneath the long shadows of a difficult childhood and the memory of a mother lost too soon, she wears only one precious thing around her neck: a blue sapphire necklace that pulses as if it has a heart of its own.
When she is kidnapped and taken to the dark realm of Dimithryus, one of the Princes of Hell, Jolie discovers her capture is no accident. Someone wanted her there. Someone had been waiting for her.

Dimithryus is cruel, possessive, wrapped in an ancient darkness. And yet, every time he looks at her, there is something in his crimson eyes that Jolie cannot explain: the precise and impossible sensation of having already been seen that way, by those very eyes, in another moment she cannot remember.
