The dead monarch Charon was destroyed at Elzinga Asylum, but its impact on the Hourglass strike team continues to affect them, particularly Clyde Williams. With his necromantic powers acting up, he’s under the watchful gaze of the Median’s rulers, fearing he could be a risk to their kingdom of sleep and the countless souls therein. But when a familiar enemy resurfaces and attacks a secret Hourglass facility, killing a high-profile Hourglass member, and stealing sensitive intel, Clyde is pulled back into service. Now, Clyde and his teammates must find and stop a powerful new threat: a troubled Spark whose anger issues could potentially lead him to being swayed by the Cairnwood Society’s dark agenda. And somewhere in the creature-filled wastes of Erebus, Kozlov continues his perilous search for the Firmament Needle. A quest whose reverberations will be felt by Clyde, his teammates, and most of all, the volatile new Spark.
