Jessica's much-deserved cruise becomes a working vacation when her friend Kathy tags along, hoping to locate her sister Wilimena, who vanished from the same vessel. Distantly related to Alaska's most famous madam-a woman who may have struck it rich during the Gold Rush-Wilimena apparently took the cruise to find the treasure.

Now, as Jessica and Kathy investigate Wilimena's disappearance, they learn that she was quite outspoken about her gold claim-and may have attracted the wrong kind of attention. And now that attention has been turned on Jessica and Kathy.
