With over 35 million online reads and a traditional publication in Poland, this story now returns in English—fully revised with a brand-new continuation in Book 2 of the Partnership Duology.
When Juliet Greene lands an internship at the luxurious Empire Heights hotel, she thinks her life is finally back on track.
Until a single encounter shatters everything.
One mistake puts her in the crosshairs of Adrian Vandermir, a cold, ruthless man with too many enemies and far too many secrets. Years ago, his parents were murdered due to a deadly partnership created by Xavier Rocillie. Adrian’s goal is simple: destroy the partnership and those who stand in the way. He’s powerful, calculating… and dangerous, and Juliet wants nothing to do with him. But when threats close in on her family, walking away is no longer an option.
To protect the people she loves, she has to play by Adrian’s rules.
But the deeper Juliet’s pulled into his world, the more twisted the truth becomes, because she’s no innocent bystander. Her family’s hidden ties make her the last piece of Adrian’s puzzle—and the one person who can end the partnership for good.
Forced into a fragile alliance, they set off on a journey where buried secrets rise, old wounds reopen, and the past and present collide.
Built on power, betrayal, and blood… their fatal alliance might be the only thing that can save them—or destroy them both.
