On the one year anniversary of parasite Anisakis Nova's first appearance, the infected launch a massive coordinated attack against cure distribution centers. In an instant, the already fragile country dissolves into chaos once again. The infected aren't just back; they're stronger and smarter than ever with world domination on their minds. Meanwhile, humans struggle to defend themselves against the infected onslaught. While some choose to recede into the mountains to start a new life, others fight to save civilization. For both, a nightmarish game of survival has only just begun. This is the second book in the Pulse trilogy.
