To say eighteen-year-old Farrah Higgins - or Digit - is good at math is a laughable understatement. She's been cracking codes since childhood, and is finally at home with "her people" at MIT in Cambridge. Her talents are so off the charts that her laptop is under surveillance by both the CIA and an eco-terrorist named Jonas Furnis. So when she thoughtlessly hacks into the Department of Defence's database, she lands in serious hot water inside and outside the law. Readers will be sad to turn the last page of this suspenseful, sassy, super smart thriller, the sequel to A Girl Named Digit.
