She made herself indispensable.
He made the mistake of thinking she would stay invisible.
Nadia Voss has spent three years running Callum Ashford's world from the outside of his office. Presentations are fixed before meetings begin. Crises are redirected before they reach his desk. Problems disappear so efficiently that no one ever thinks to ask who solved them.
Callum Ashford expects excellence. He does not say thank you for what should already be done. He does not mistake competence for intimacy. And he certainly does not notice the quiet architecture Nadia has built around his success.
Until someone else does.
When recruiters and rivals begin offering Nadia the title, salary, and recognition Ashford Partners never gave her, Callum is forced to confront a problem he cannot solve with pressure, precision, or money alone.
Nadia is not leaving because she failed.
She is leaving because she finally understands her value.
And Callum Ashford, ruthless investor, impossible boss, and the last man she should want approval from, is about to discover that seeing her may cost him more than he expected.
The Assistant is Book One in Devil in a Suit, a billionaire office romance series featuring a ruthless boss, an overlooked but brilliant assistant, slow-burn workplace tension, power imbalance, professional ambition, jealousy, emotional restraint, and a high-stakes corporate world where the most dangerous deal may be the one neither of them meant to make.
