Summoned by the Capo's Warlock

Marisol Duarte finds hidden money for a living. The Corvino family finds her in three days, puts her on a plane, and asks her to locate two hundred million euros their late capo has apparently walled into a house in Calabria. The house is not on the map. It is warm. It has been in the family since 1743, and so has Don Ottavio, the warlock who runs it, who calls Marisol by her grandmother's name and means it as a compliment. Matteo Corvino, the new capo, wants her to find the money and leave alive. The house wants an accountant who never walks out. Marisol has one year to write it a balance it cannot survive. A dark gothic mafia romance of cold money, older houses, and the one woman who did the maths.
