When cybersecurity consultant Simone Delacroix walks into Morrison Capital Partners to investigate a data breach, she expects to find the usual corporate negligence. What she doesn't expect is Alex Morrison—the firm's CEO, a man trapped in a perfect marriage that stopped meaning anything years ago. He's polished, powerful, and completely unprepared for a woman who calls him a liability to his face before her first coffee goes cold.

As Simone pulls the threads of the breach, the evidence points somewhere no one saw coming—and someone inside the firm will do anything to make sure she stops looking. But the investigation isn't the only thing unraveling. Simone and Alex have crossed every professional line that exists, and the closer she gets to the truth, the more dangerous the lies become. Both of their marriages are fracturing. The people closest to them are watching. And the secrets Simone uncovers will force everyone in the building to choose a side.

Set against the steel-and-glass towers of Chicago's financial district, Zealous Ruin is a fast-burning romance thriller about two people who find each other at the worst possible time—and refuse to let go. It's a story about dead marriages, dangerous secrets, corporate betrayal, and the terrifying act of choosing honesty when it costs you everything.
