He ripped me from my life and made me his. Now he wants my help. But some sins can never be forgiven.
Matvei Morozov.
A name that’s haunted my family for years.
A whisper in the shadows. A monster in the darkness.

Now, the billionaire mob boss has claimed me as collateral.
That means I’m his—until my father pays his debts.
His to touch.
His to bend.
His to own.

But Matvei wants more than just me on my knees.
And when he drags me to his mansion, I see what the don is hiding:

An innocent child who needs my help.

Matvei Morozov, the single dad?
Nothing makes sense anymore.

He wants me to help him raise the boy.
But the more I submit to what the don wants, the more pressing one question becomes:
If I fall deeper into Matvei’s world…
Will he ever let me go?

Sins He Taught Me is a full-length, standalone single dad mafia romance novel in the Bratva Crime Syndicate series.
