And it is, until the zombie exterminators find out that the creepers in their neck of the woods happen to be switching the game up a bit. They have a new nifty trick that keeps them from being readily recognizable. Something poor Poppy is unlucky enough to find out on her morning run. She goes from fantasizing about her birthday foursome with the boys, to running home to spread the bad news of mutation. Her big day is suddenly full of machetes, a lady from the CDC and news of a new vaccine that might—or might not—work. Lucky for Poppy the boys won't let the new turn of events ruin her birthday, they still take her where she needs to go. Because all four of them know, every day could be your last. Sadly, Garrity, Cahill and Noah can't control what happens next. Things change, possibly forever, for their little group of exterminators. And over the next few days Poppy realizes a few things with perfect clarity: she loves Garrity, the thought of losing one of the boys terrifies her, and she's completely at a loss when it comes to one of her own being threatened. It seems to be the one area in which she can't pull off the bad ass persona. What will she do, she wonders, if their perfect group of four suddenly becomes a group of three? How will she survive?
