Tory Brennan and the rest of the Morris Island gang are tracking a pack of rogue Virals who call themselves the Trinity. The new pack was infected by a strain of supervirus created by Tory's nemesis and sometimes-crush, Chance Clayborne, who accidentally infected himself, too. These red-eyed Virals have openly challenged Tory's pack for domination of Charleston, and they'll stop at nothing to bring their rivals down, even if that means giving them up to a shadowy government agency.
