Years after her husband's death, Celine Hasket still visits his grave every day. There, she talks to Gabriel, and he replies through the breeze, butterflies, and the bird chirping high in the oak tree that shelters his resting place.

Despite her grief, Celine has forged a new life for herself from the ruins of his murder. Yet her days are monotonous, her future bleak. Everything changes when a steamy tryst at a masquerade awakens long-forgotten desires—and sparks a memory that may help her uncover her late husband's killer.

Newly motivated, Celine begins an investigation with an unlikely ally who proves most distracting with his sharp cheekbones and brilliant eyes.

But passion isn't the only revelation of her investigation. As danger grows ever nearer, Celine will have to choose whether to risk her heart again or grow old with Gabriel's ghost—before his killer makes the choice for her.
