The book is a work of fiction. It is about the arrival of suicide bombing in America and the dedication of the men and women of the FBI, CIA and local authorities who put their lives on hold to pursue those involved. When the New Year's Eve celebration in Times Square ended with a blast, it got the attention of Hiram Sloan of the FBI's Terrorist Investigation Unit and his wife, Janet, a CIA operative. When fragments of a suicide bomber turned up in Times Square, it led to an exhausting and relentless pursuit of those who would engineer catastrophic events on American soil.
