OK, go easy on a first time poster as I have a feeling I may have missed something obvious.
I’ve just finished reading the first book - fantastic read and beautiful art - and I thought that the group that went to the island and were given super powers were the only super-powered humans on Earth (until they had kids who also had super powers).
But at one point in the book there’s a big battle and there are a lot of other guys with super powers. Who were they? Were they all children of the original group?
It’s been bugging me for days.
