This is a dnf for me. My expectations of this book didn't quite match to the reality. I usually jump at the chance to read hacker books because I've enjoyed so many of them. I'm a fan of the nerdy characters. While Hannah was a hacker she didn't quite fit the bill of nerd. I can adjust, but there were just a few things in the story that wasn't believable to me and really made it hard for me to connect to it. The book is well written, but not a great storyline. 
 (view spoiler)[ I had two main issues with this book. 1) the plot. She lost her dad to a car accident due to road conditions. Her sister was in the car and is disabled now. She believes the government cut corners to save money and that's why the road conditions were bad. I just can't really buy that as a plot. 2). The author shows Hannah getting her start as a hacker in college when her roommate teaches her how to fix her grades then later in life she's so good the FBI are having trouble tracking her down. Maybe if she was a hacker her whole life...but not if she had to be taught how to fix her grades in College. (hide spoiler)]
