Tales of Sinanju: The Destroyer, book five "Death Dance"

THE MOST TERRIBLE DANCE OF ALL - The whole world watches the awful destruction and climbing death count in the wake of the devastating earthquake that reduced Japan to rubble. But an otherworldly set of eyes also watches, and schemes, as Kali the Terrible uses the radiation spill from the Fukushima reactor leak to plan the ultimate dance and spread destruction worldwide. A desperate Harold Smith wants to stop the problem at its source, but not even the House of Sinanju can stop deadly waves of radiation spillage... especially when it comes with a murderous dark goddess in tow.
