Aristina Bianca Rosen is the most notorious villainess in the entire empire, so it's no surprise that someone has tried to kill her. But little does everyone know that her body has been possessed by an avid mystery novel reader! And with the resources of a noble aristocrat, she can investigate who her attempted killer is to her heart's content. But if her top suspects are a cold crown prince, a scornful second prince, and a prickly high priest, can money really get to the bottom of this mystery? (Source: Tapas)
