This book picks up where the third book in the series, "The Ninth Day", left off. It is an action-packed, fast-paced story, with a plot that is pulled from the headlines, but it also has the kind of telling scientific detail that readers find so fascinating. Jamie Freveletti has the perfect research skills to bring her stories to life. Perfect for fans of Lee Child, Daniel Silva, Kathy Reichs, and Tess Gerritsen.
