Agatha Cole didn't marry for love. She married into one of the most powerful families in the city, and she knew exactly what that meant look the part, say the right things, and never overstep. She was fine with that. Until the night everything changed. At a high-stakes gala where two wealthy families are competing for a multi-million dollar business deal, Agatha does something no one saw coming. She speaks up. And it works. But someone noticed. Vivienne Laurent is beautiful, calculated, and used to getting what she wants. She came to the party to win the deal for her own family and to size up the competition. What she didn't expect was Agatha. Now these two women are caught in something neither of them planned for. Not quite enemies. Not quite allies. And dangerously curious about each other. Meanwhile, Agatha is starting to ask questions about her own husband questions she isn't sure she wants the answers to. House of Cole is a story about power, secrets, and what happens when a woman who was never meant to be the main character decides she is.
