The pandemic has receded and life in the United States has returned to normal-or that's what the government insists. So what is causing residents in a remote religious compound in Idaho to drop dead in a grisly fashion? And why are prominent virologists meeting with untimely ends?

Something-or someone-is killing the religious followers and scientists, and Newshound reporter Nik Byron is determined to find out what's behind the deaths. Could Xion Labs' top-secret vaccine program be connected? Nik suspects so, but he's being stonewalled at every turn. As he inches closer to the truth, Nik's professional enemies move to quash his investigation, threaten his career, and destroy his personal life. With his world crumbling, Nik finds one last lead: Puck Hall, a resolute, free-spirited young woman and Xion Labs researcher, who is soloing the Appalachian Trail. It's only when Puck, barely clinging to life after eluding trained killers, crawls out of the wilderness that Nik and a rookie reporter cobble together the nightmarish facts that bring the story into focus.

Populated with old-school journalists, double-crossing politicians, black-ops assassins, and government secrets, Black Bird follows Nik Byron on a thrilling investigative journey along the Appalachian Trail, deep into the northern Rocky Mountains, over the Pacific Ocean, and eventually right to the doorstep of the White House.
