Catalyst | Peter Parker

Peter Parker knows Blair Mercer's secret.

Blair Mercer had no idea Peter Parker is Spider-Man.

That would probably be complicated enough if they weren't also competing for first place at Midtown.

To everyone else, Blair Mercer is exactly what she appears to be: clever, stubborn, painfully competitive and entirely ordinary. Only a handful of people know that Mercer isn't really her name, that Bruce Banner is her father, or that the abilities she's spent years learning to control belong to the masked identity known a Vesper.

Peter happens to know all three.

Blair, unfortunately, just thinks he's being weird.

But secrets have a habit of becoming harder to keep when two lives begin colliding. And Peter and Blair are about to discover that sometimes, all it takes is one person to change the course of everything.
