The Ghost Ship

In this cozy mystery, teenage sleuth Nancy Keene accompanies her father and friend Bess to the Queen Mary during the Art Deco Festival. They book a ghost tour where Nancy's father is kidnapped. Where did he go? Who did this to him? Will Nancy be able to figure it out on her own, or will she enlist the help of her friends, especially since she's confined to a walker after fracturing her pelvis. She must rely on her wits while her friends will be the ones searching secret rooms and looking for hidden staircases, much to their own peril.
