Billionaire Daddy’s Girl by Lena Little

I only planned on picking up my niece from kindergarten, ready to treat her to ice cream and whatever new toy she’s got her eye on, but when I set eyes on the new teacher, my world shifts on its axis.
As a well-connected billionaire and CEO of multiple companies, there’s nothing I don’t have … except love.
One look at Delaney Graeme, and I know she’s mine.
But Delaney’s never had anyone to take care of her before and convincing her she’s worth everything I want to give her, and more, isn’t easy.
Being powerful means I have enemies, and when one of them threatens to come after my girl, there’s nothing I won’t do to keep her safe.
I promised to take care of her, and I don’t break my promises.
Especially not to her.
