When scientists brought dragons to life, people flocked to see them, including Zelda Rissland. Unfortunately there were side effects. A deadly parasite was unleashed: Wyrmrot. First, it ate peoples' brains, and then it made them eat each other. Losing her brother, and then her entire family, to the zombie apocalypse, the only person Zelda has left is her boyfriend, Cooper Marotta. Together they carve out a safe place, but they're running out of food. So, when mysterious coordinates appear on a construction sign, Zelda knows there is only one thing to do: follow them.
