Two hours to vanish. One chance to escape. Zero alternatives… Ten Americans have been carefully selected to Beta test a ground-breaking piece of spyware. FUSION can track anyone on earth. But does it work? For one contestant, an unassuming Boston librarian named Kaitlyn Day, the stakes are far higher than money, and her reasons for entering the test more personal than anyone imagines. When the timer hits zero, there will only be one winner… From four-time Academy Award-nominated screenwriter Anthony McCarten comes a breakneck, wickedly entertaining thriller for our times, a twisty, action-packed novel reminiscent of the best Michael Crichton technothrillers.
