FBI profiler Karen Vail returns in Velocity, national-bestselling author Alan Jacobson's most explosive thriller to date Vail's boyfriend, Detective Robby Hernandez, has seemingly disappeared into the dense air of a Napa Valley evening. There are no clues to his whereabouts, other than a blood stain-and potential connections to a serial killer operating in the wine country. Despite using all means at her disposal to find out what happened to Robby, Vail's efforts are thwarted until her colleague, Detective Paul Bledsoe, hooks her up with Hector DeSantos, a covert Defense Department operative who has a knack for finding difficult to locate information. But DeSantos is an unwilling partner, and other than offering superficial cooperation to pay back the debt he owes Bledsoe, he is reluctant to work his valuable informants for what he views as Vail's personal crusade to find her lover. That is, until Vail pries loose long-buried secrets, lies, and deceptions on the part of her own task force members. It's information that even DeSantos can't ignore, a discovery of great magnitude that reveals larger forces at play-forces that propel Vail and DeSantos into a frantic search that takes them from the wineries of Napa Valley to the monuments of Washington, DC, from the wealthy beach enclaves of San Diego to the bright excesses of Las Vegas. "From the first page, Velocity is as relentless as a bullet. Karen Vail is my kind of hero and Alan Jacobson is my kind of writer " -Michael Connelly, New York Times-bestselling author "Jacobson captures the complexity of the mission faced by DEA, the threat posed to our country, and the constant danger our agents face battling members of international drug trafficking organizations. As someone who devoted his career to carrying out that mission, I can say first-hand that Velocity hits the target. Jacobson's acquired a new fan." -Supervisory Special Agent Michael Upchurch, Drug Enforcement Administration "Jacobson writes for suspense junkies and gets the monkey off their backs; he's that good." -New York Journal of Books
