Moving target : a novel / J.A. Jance.

Enhanced descriptions from Syndetics:

In this instant New York Times bestseller and high-stakes thriller Ali Reynolds spans continents to solve a cold case murder and to figure out who wants a young juvenile offender dead.

EVEN GHOSTS CAN'T HIDE FOREVER.

Lance Tucker, an incarcerated juvenile offender doing time for expertly hacking into the San Leandro School District's computer system, is set on fire and severely burned one night while hanging Christmas decorations in a lockup rec room. The police say that he did it to himself, but B. Simpson, Ali Reynolds's fiancé and the man who helped put Lance in jail, feels obligated to get to the bottom of what really happened.

Lance is famous in the hacker world for developing GHOST, computer software that allows users to surf any part of the web completely undetected. And that kind of digital camouflage is seductive to criminal minds who will stop at nothing to get their hands on this revolutionary-and dangerous-technology.

Meanwhile, in England, Ali investigates the decades-old murder of Leland Brooks's father, which Leland himself was once suspected of committing. With Ali otherwise occupied and Lance receiving cryptic threats in the hospital, B. turns to Sister Anselm-a Taser-carrying nun and Ali's close friend-for help protecting the boy. With unsolved crimes on both sides of the Atlantic, Ali, B., and Sister Anselm are united by their search for answers-though being thousands of miles away may not be far enough to keep Ali from being drawn into the deadly line of fire.

From the New York Times bestselling author hailed for her "inimitable, take-no-prisoners style" ( Kirkus Reviews ), Moving Target sends Ali on a transatlantic adventure and straight into the path of a ruthless killer.
