   Summary

   Duke Thomas: A Totally Normal™ teenager (and not a superpowered daytime vigilante).
   Billy Batson: A Completely Harmless™ young boy (and not secretly the Champion of Magic).
   Percy Jackson: Very much NOT a human being. Seriously, what is up with that guy?

   They've never met, and if things were different they never would have. But what happens in the universe where their paths do cross? (When in doubt, blame everything on Greek mythology.)
