Ten Americans have been carefully selected to Beta test a ground-breaking piece of spyware. The goal is to disappear off the grid and evade FUSION, which can track anyone on earth. Cy Baxter is the creator of FUSION and if his softwear succeeds, he earns a ninety-billion-dollar government contract. If a contestant wins, they earn three million dollars. 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.
