The world of technology is always changing, but does it always change for the better? The subjects of government experiment, code named "Addition", are finding all news ways of answering this question. Lynn Dane, the Orphan, found a home with her errant-minded best friends Michael Dane, the Boy Left Behind, and Grace Lillybridge, the Rich Girl. All three with such imaginations that they could touch the outer planets. But when a recruiter for a new governmental project captures their attention, Michael pulls the two of them into something that won't just change their life, but will turn it upside down and make it soar. But will they soar beyond the skies, or will their Additions make them fall?
