"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? Each participant is given two hourse to "go zero"- to go off-grid and disappear- then thirty days to elude the highly sophisticated capture teams. 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."-- adapted from jacket.
