In the Small by Michael Hague
"A mysterious blue light (given the name "The Blue Flash") instantly reduces every human being on Earth - and ONLY human beings - to one-twelfth of its original size, so a six foot tall person is now a six INCH tall person. In a (literal) flash, Nature turns the tables on Mankind: Machines and dwellings made for Man's use are now too big to be used, devices to keep nature at bay are either useless or keep humans at bay now. And Man is no longer the dominant creature on the planet; even creatures still smaller than humans, such as ants, are more deadly than they were before. Among those who survive the Blue Flash, two brave teenagers, eighteen-year-old Mouse and his sister Beat, emerge as leaders. This graphic novel has been out for almost two years, and reportedly there are plans for a motion picture based on it."
Sound interesting.
Seem to be a movie of it planned for 2010 by the guy who make "I am legend"
