Dax Daley is on his way to prison. But it turns out prison is actually a school - for superheroes! 40 superheroes, to be exact. But Dax - Number 41 - does not belong. He can't turn himself invisible. Or see in the dark. Or read minds. And he definitely will not fight the strange things looming around the corners of Scragmoor Prime. Because Dax Daley doesn't have any superpowers... yet!
