Keeper of Secrets by Tammy Andresen

A fake marriage to a cold DUKE is the last thing she wanted…
He’s a scoundrel.
A wastrel.
The man who just ruined her.
And worst of all…he’s her new guardian.

The moment Ryker, the Duke of Helmsworth meets Chloe Fairchild everything changes.
Not because with a single look, he falls in love. That horse s**t is for fairytales.
She’s half his age and so sweetly innocent she makes his teeth hurt.
She was meant to be a simple diversion. One little taste of decadent temptation in a world so dark and bitter.
But that was when he learned the truth.
Chloe wasn’t just some random girl meant for fun, she was his new charge. The very innocent he’d been tasked with protecting. The one woman he should never touch.
Too bad he’s had a taste. And Chloe…
She is delicious.
