MAESTRA by L. S. Hinton

A very different book.  Not quite FIFTY SHADES but not a simple mystery either.  Judith came from poverty but would not accept that as an adult.  She wanted everything she never had.  But, until she ran into an old school chum, she wasn't sure that would happen.  Whe Judith met the rich men in the gentlemen's club, she saw how she would handle her new status.  But, the first death she witnessed gave her an insatiable appetite for murder and more.  Be prepared for shocking and ruthless scenes.
