Duel for the Doctor — Lynne Collins

Her sister was the magnet that drew the young and attractive Dr. Marlow to the Manor House ... or so it seemed to the shy and sensitive Jessamay who realized the futility of wanting a man once the beautiful Serene had staked a claim to him. For the cool, self-possessed and sophisticated sister had always achieved everything she wanted in life ... and Jessamay lacked the confidence to step out of Serene's shadow and into the sunlight of her own right to be noticed and admired by men. But it was a poor kind of love that could not reach out for happiness although she did not really hope to win the duel for the handsome doctor.
