Something large hits the water behind me, human-sized and bewildered, struggling out of a blanket in the water, retching blood and brine. Stella. It is a marriage of sorts, I suppose, in the most ancient of Greek ways, wedding of blood and salt. Now the game becomes more complex—if we split up, almost impossibly so. With the right limits on speed, one of us almost certainly survives. On the other hand, an ordinary great white shark can reach speeds of up to fifty-five kilometres per hour. Who knows how fast a god-shark can move, if she wants to be somewhere?
