The recently transplanted Order of the Illumination of the Sacred Virgin -- a sisterhood well-known, for having witnessed actual, Vatican-verified miracles -- is predicting yet another miraculous event, scheduled to take place in Miami in one month's time. And Lupe Salano has been hired to either substantiate the upcoming phenomenon's verity or expose a brazen hoax and its mastermind. Yet Lupe believes that probable fraud is the very least of the sins possibly being committed -- a belief that is strengthened by the disappearance of the Order's enigmatic Sister Mary Margaret and the appearance of a dead body floating in the waters of Biscayne Bay. As the date of the anticipated wondrous event draws closer, Lupe's hunt for the truth and a killer becomes a race against time. For there is a dark secret being protected behind the convent's fortress-like walls. And more will surely die unless one determined investigator can unveil an evil that may be taking refuge in the most sacred of places.
