Young, prodigious Metropolitan Opera violinist Julia Kogan, having survived her entanglement in an investigation of her mentor's murder and a subsequent violent, life-threatening attack of a ruthless killer, is called upon for a key musical leadership position at the Santa Fe Opera. But at the spectacular outdoor theatre in the shadows of the mysterious New Mexican Sangre de Cristo Mountains, she witnesses yet other operatic murders, both onstage and off. Dark and painful secrets emerge as, ignoring warnings from her colleagues and from Larry, her significant other, Julia plunges into her own investigation of the killing. Ghostly apparitions combine with some of the most bloody and violent operas in the repertoire to make Julia question her own motives for searching for the killer. But this time, the threat to her life originates from a source she never would have imagined.
