Lost City of Steam — R.L. Edinger

On the eve of Queen Victoria's death, Rory Breckenridge and twenty other families disappeared in a great storm on the Irish Sea. One hundred years later eight college students vanished while exploring the Breckenridge estate. A young woman, Leara, searches for her sister who was among them. Unable to find her sister, she seeks out the one person who can help, Private Investigator Andrew Knight. What starts out as a simple missing person's case turns out to be much more. When the truth is finally discovered, Andrew Knight may be the one truly in danger.
