In the gripping 13th installment of the Jeannie Loomis series, FBI agent Loomis finds herself embroiled in yet another high-stakes investigation at the behest of Interpol. This time, the elusive mastermind and their cohorts have brazenly pilfered the Sudarium of Oviedo, a revered artifact said to have shrouded the face of Jesus post-crucifixion, from its sanctuary in Spain. But before Loomis can close in on the perpetrator, another sacred relic, the Shroud of Turin, vanishes without a trace.

Haunted by a terminal diagnosis, Loomis is driven by the urgency of solving what may be her final case. Yet, as she and her steadfast partner, Ismail Flores, race against time, the criminals outmaneuver them at every turn. Their audacious theft of the True Cross, a fragment of the very crucifix upon which Jesus was executed, raises the stakes to unprecedented heights.

From the ancient streets of Rome to the majestic landscapes of Spain, and ultimately to the sacred grounds of Jerusalem, Loomis and Flores embark on a perilous quest to reclaim the stolen relics and thwart the nefarious designs of the criminal syndicate. Will Loomis's indomitable spirit and unwavering determination be enough to bring the perpetrators to justice and safeguard these holiest of treasures?
