No Immunity

When two immigrant boys die of a brutal and mysterious illness, Kiernan must fight to prevent an outbreak. This audiobook is narrated using advanced digital voice technology for clear, natural-sounding storytelling. Deaf and incapable of speech, the two children from Panama are unable to voice their suffering, but Grady can tell they are dying. When he met them in the jungle they were miracle workers, soundlessly leading him and his team to the richest geological find of the century, and he brought them back to Las Vegas to safeguard his investment. Unwilling to hospitalize the children and risk deportation, he gets them out of town to die their tortured deaths. Whatever killed them is mysterious, uncontrollable, and ready to sweep across the region. The only person who can stop the impending epidemic is Kiernan O'Shaughnessy, medical examiner turned private detective, who once led a losing fight against a similar disease in Africa. She goes to Nevada to fight the outbreak, but finds herself battling greedy geologists and her well-meaning but hapless former houseman instead. If she can't contain the fever quickly, Nevada could find itself on the brink of a deadly disaster. No Immunity is the 4th book in the Kiernan O'Shaughnessy Mysteries, but you may enjoy reading the series in any order.
