On the shore of an anonymous pond in southern Ontario, far away from any possible observers, two teenage boys are playing tag.

This would not be all that remarkable, except for the fact that they're moving at more than twice the speed of sound.

The air roils and thrashes in their wake, but it only takes them a few minutes to learn how to avoid sonic booms. After that, the game is much quieter.

Both boys are wearing modified speed-skating skinsuits and hand-sewn masks, one in blue accented with smooth arcs of silver, the other in black with jagged streaks of gold. Ten minutes into the game, black-and-gold darts out onto the surface of the lake.
