I just came across a web site entited
The Bekka Effect, which has this terrific subhead: Endowed With Special Powers Since Puberty. I like that. Reminds me of the throwaway line from X Men (and no, I didn't see either of the sequels, though I'd like to) where the kids are playing some game off in the field, and one aggrieved young voice can be heard shouting "Hey, No Powers!"
