For those who were left breathlessly awaiting the conclusion of rogue FBI agent Jane Hawk's plight depicted earlier this year in The Silent Corner, the release of this sequel can't come too soon. Jane, readers will recall, was seeking an explanation for her husband Nick's unanticipated suicide when she discovered a bizarre network of similar deaths across the country that set her on a quest to locate a common source. Her clandestine investigation led to the discovery of a sinister group employing nanotechnology to control the actions of an alarming number of individuals without their knowledge or consent and to her suspension from the FBI. In this second volume of Koontz's new series, Jane's mission is retribution. Employing her impressive skill set that combines tech-savviness with physical prowess, she methodically pursues the powerful and evil masterminds behind this malevolent conspiracy, hoping to put an end to the destruction it has caused. The results she achieves both satisfy and leave the door open for Jane's promised return. Verdict Koontz delivers another winner.
