Sev, her friends, and an unlikely ally must team up in order to find the cure for Sleeping Sickness that Sev's mother developed, before Dr. Yang can use it to blackmail people into submitting to his rule.
Sev must decode her mother’s last words to find the cure to Sleeping Sickness before her enemies find it first in this stunning sequel to Last Star Burning, which #1 New York Times bestselling author Aprilynne Pike calls “a rich and timely tale.”No one is safe, not with a horrifying new strain of Sleeping Sickness tearing through the population. After fleeing the City with her friends, Sev has one goal: to find the cure her mother developed and put an end to the epidemic once and for all. But decoding her mother’s last words—to seek out “Port North”—is easier said than done. Nobody she talks to has heard of Port North, and with only Tai-ge and June on her side, Sev fears Dr. Yang will find the cure first, and that he’ll use it to start a new world order under his rule. With no leads, Sev is running out of options—until she discovers someone hiding in the cargo hold of her heli plane. Someone she thought was dead. Someone with maps that could point the way to Port North, if only she could read them. Unfortunately, the one person Sev never wants to see again might be the one person who can help her find the cure.
