She signed a contract with a devil. The fine print could destroy them both.

Elowen "Ellie" Merrick never expected Lucian D'Aramitz—billionaire media mogul and Paris's most ruthless bachelor—to stride into her bookshop with an offer she couldn't refuse.

Thirty days as his fake fiancée in exchange for her brother's freedom from a deadly debt. The terms were simple: play the loving couple, secure his inheritance, and walk away. But the moment Lucian's lips brush hers in front of the cameras, the lines between pretense and passion blur.

The stakes? Higher than the cliffs of his Breton estate.

As Ellie navigates gilded ballrooms and whispered threats, she discovers Lucian's world is built on lies—including the contract with her name signed before they met. His vengeful ex-fiancée plants scandals, his uncle's sniper waits in the shadows, and every touch from Lucian burns hotter than his secrets. When Ellie uncovers a vault containing a wedding dress in her exact measurements, she realizes:

This game was rigged from the start.

Now, with midnight ticking down and a gun pressed to her brother's temple, Ellie must choose—trust the man who's stolen her heart, or become another casualty in a war older than their love.

The real contract? Survival.

Will Ellie risk everything for a love that might be the greatest lie of all?

When the final secret is revealed, will there be anything left to save?
