If you love scandals, lies, secrets, and mystery, Zero Day by Jan Gangsei is the book for you. Zero Day is a young-adult mystery thriller that draws readers in. The story starts off with the most notorious kidnapping of the decade: the kidnapping of Addie Webster. Addie vanished without a trace and it forced her high-profile parents to move on in their political world. Fast-forward eight years, Addie’s father is now the President of the United States. Then, Addie appears again as a quiet, shy, 16-year-old girl who is brought back into her family’s life. The timing of her reappearance causes strife because the NSA believes Addie to be a threat to national security. The story acquires additional thriller moments when Addie’s childhood friend Darrow Fergusson agrees to spy on her. Darrow is a brave, loyal, and caring friend. The story questions how much is Addie a victim. There’s lots of details about espionage and lots of action. I would recommend Zero Day by Jan Gangsei for others to read.
