USA Today bestselling author Christi Caldwell pits a fiercely independent beauty against a devilish investigator.

Set apart by her ethereal beauty and fearless demeanor, Ophelia Killoran has always been a mystery to those around her—and a woman they underestimated. No one would guess that she spends her nights protecting the street urchins of St. Giles. Ophelia knows what horrors these children face. As a young girl, she faced those horrors herself, and she would have died…if not for the orphan boy who saved her life.

A notorious investigator, Connor Steele never expected to encounter Ophelia Killoran on his latest case. It has been years since he sacrificed himself for her. Now, she hires orphans from the street to work in her brother's gaming hell. But where does she find the children…and what are her intentions?

Ophelia and Connor are at odds. After all, Connor now serves the nobility, and that is a class of people Ophelia knows firsthand not to trust. But if they can set aside their misgivings and work together, they may discover that their purposes—and their hearts—are perfectly aligned.
