Double Digit by Annabel Monaghan

3.0

Sequel to A Girl Named Digit but with a lot less action and adventure than the first one.
Digit has gone off to college at MIT where her math nerdiness is much more acceptable, expected even. She and John try the long distance relationship thing. And the Jonah Furnas gang has figured out where she is and have evil intent for her mad skills.
