The third installment in The Doomsday Archives brings back an old occult relic with a new twist—it has evolved to hunt its victims via online spaces.

Of the three young members of the Order, Serena is the most sensitive to otherworldly forces. It’s a “gift” she regards dubiously. But when a student at her school dies after posting a disturbing online rant—one that appears uncharacteristic with his character—she begins to sense that something is amiss. Her search leads her to a mysterious online streamer who seems to attract promising young people just before they suffer very public breakdowns.

Could the streamer somehow be causing their declines? Things go from bad to worse when Serena discovers the stream’s newest target: her brother, Dom. Serena must face off against the Shadowglass before she loses someone she loves.
