Silver Fox Billionaire's Fake Vows
(2026)(The first book in the Ruthless Silver Fox Billionaires series)
A novel by Abby Astor
I fake married my best friend’s father… and now I can’t walk away.
Ronan Graves is a silver fox billionaire who controls everything.
His empire. His reputation. His emotions.
After his wife’s death, he only cares about one thing.
His daughter, Piper… my best friend.
One desperate call from a grieving Piper puts me inside his estate and directly in his path.
I didn’t expect the constant tension between us.
Or the way we clash over every rule he sets.
Then a custody battle threatens to take Piper away.
Ronan offers a solution.
A fake marriage.
A contract.
No feelings.
But somewhere between the rules and the nights we break them, this stops being pretend.
Now someone inside the estate is betraying us.
And just as I’m falling for him, I find out I’m carrying his child.
