Emily Wilson has spent her whole life trying to outrun her father’s name. A scandal destroyed him, and the world never let her forget it. Julian St. Clair is the ruthless billionaire CEO of St. Clair International. Cold, calculating, and untouchable, he lives by one rule: trust no one. When an anonymous file lands on Emily’s desk, its final page bears a single name: Julian’s. She expects an enemy. Instead, one dangerous encounter ignites an attraction neither of them can control. Julian knows she’s investigating him. Emily knows he’s hiding something. So they make a deal: a secret affair with four rules. No love. No jealousy. No questions about the past. No future. But rules are made to be broken, and their families have been tangled together for far longer than either of them knows. The closer they get, the more dangerous the truth becomes. It began as a battle. It became an affair. Now it’s the one thing powerful enough to destroy them both.
