The Overture of Fear & Desire - The Daemonica Symphony Series, #1

Juliet Vassilios has always trusted the simple version of her life: a gifted violinist, stubbornly human, doing whatever it takes to scrape by while carrying her father's grief and her own. That illusion shatters when she's attacked by a stranger with impossible strength… and she fights him off with a power she didn't know she had.
When her estranged grandmother arrives, Juliet is left with more questions than answers. Searching for the truth leads her to the remote Livingstone Institute, a secluded Romanian castle where demons, shifters, and the hidden elite of the Otherworld train under ancient, unforgiving laws. Juliet is meant to learn control. Instead, she finds danger, hunger, and Niko Dmitriyev, the one person she can't seem to stay away from.
Niko recognises Juliet the moment he sees her. Not her face. Not her music. Her soul. She is the key to breaking a destiny he's spent his life trying to outrun. Claiming her could save him. Losing her could destroy them both.
But something older than destiny is stirring beneath Livingstone. A presence drawn to Juliet's blood… and to the music only she can summon.
When a friend is murdered, she and Niko are forced together in a race to uncover the truth. What they find is a creature who has waited centuries for release, a being of fear, desire, and ruin, and it has already set its sights on Juliet.
The Overture of Fear and Desire begins the sweeping Daemonica Symphony, where music is power, monsters wear familiar faces, and love is as dangerous as the dark.
