Fireworks at Dusk

In a city divided by a deep river valley, one side is stricken with a deadly outbreak. In order to protect themselves, the citizens on the other side of the valley destroy the connecting bridges and sever all transportation and communications links. Brielle lives on the western side of the city in the epicenter of the outbreak. Rayden is a native of the east side. On the eve of the outbreak, he's on his way to see Brielle when the two sides of the city are separated.
With little information getting out, and no way to contact her, he's desperate to know if Brielle is safe. Even though the odds are stacked against them, the two lovers find an ingenious way to reconnect.
