Harmony - Volume 4 - Omen

Harmony and her friends have been taken to a peaceful and secure location, away from the medical experiments and grueling training sessions forced on them by their former captors. But Harmony can't help feeling her new "guardians" are keeping something from them, and when young Eden starts having terrible nightmares, she unwittingly sets off a chain of events that prove that Harmony wasn't entirely wrong to be mistrustful.
