From a USA Today–bestselling author: FBI profiler Karen Vail’s hunt for a serial killer leads her into a dangerous criminal web—“relentless as a bullet” (Michael Connelly).
After a colleague connects Vail with covert Department of Defense operative Hector DeSantos, who has a knack for uncovering difficult-to-locate information, the pair pries loose long-buried secrets and deceptions that reveal a much-larger criminal enterprise at work. As Vail squares off against foes more dangerous than any she has yet encountered, shocking personal and professional truths emerge—truths that may be more than she can handle.
In keeping with Alan Jacobson’s page-turning style, Velocity is a high-octane thriller, a memorable work rich in believable characters and an intricately plotted story that’s well-researched and ripped from today’s headlines. Velocity was named one of the Strand Magazine’s top ten books for 2010, Suspense Magazine’s top five thrillers of 2010, Library Journal’s top five thrillers of the year, and the Los Angeles Times’ top picks of the year.
 
Velocity is the second installment of a two-part story that begins with Crush, book two of the Karen Vail Series.
