Sometimes a single action is enough to turn everything upside down. That’s what happened with Inga, who didn’t walk past someone else’s trouble—her life split into “before” and “after.” The man she helped, however, turned out to be strange. More than that, since the moment they met, Inga became alien to her world—infected. A threat that must be eliminated. And now, in order to survive, she’ll have to follow a mysterious stranger, with the path for her shown by the most ordinary tablet—an alter tablet that once brought that strange guest to Earth.
