The PROJECT VALENTINE series
The Valentine family empire is evolving and after retiring from the Valentine Corporation, the family matriarch sets about seeking HEAs for her three billionaire sons, Victor, Vance and Vaughn.
Read all three stories in the series. But each can be read as a standalone book.

Her JEALOUS VALENTINE:
VICTOR
I’m a king. A conqueror.
Head of a multinational enterprise best described as the Valentine Empire, more than some silly corporation.
It’s a title I’ve worked for since my father’s passing. And with my mother’s sudden retirement earlier this year, I hold the keys to this castle.
So why do I want to give it all up?
Olivia, the blue-eyed beauty who turned my world upside down and taught me the greatest lesson I’ll ever learn. Life doesn’t have to be one big race.
With her, I want to slow it down.
Rest my head.
Fall in love.
Start a family.
All those beautiful things that used to sound like a cheap ad campaign to sell diamond rings.
Well, buddy, I’m falling for the marketing.
And I’m going to buy her the biggest ring I can find.
