Only days have passed since a freak accident granted four college students superhuman powers. Now Jools and her friends (who haven't even picked out a name for their superhero team yet) get caught up in the hunt for a Mad Genius's misplaced super-weapon. But when Jools falls in with a modern-day Robin Hood and his band of super-powered Merry Men, she finds it hard to sort out the Good Guys from the Bad Guys - and to figure out which side she truly belong on.

Especially since nobody knows exactly what the Gun does.
