A time of loneliness. A task to fulfill. A heart to break. Things have been peaceful for the past three months in Apollo City. And while this would normally make Hamilton Dinger happy, Raiya's sudden departure leaves him irritated and angry. Despite the decrease in crime and attacks, Hamilton knows it is only a matter of time before the remaining Sinisters and their mysterious new leader cause more trouble for him. When Alora comes under attack, Hamilton and his team, with help from his new friend, Mary, set off with St. Brendan the Navigator to restore the flow of time. But it is only after they work to save Time do they realize how little of it they have left.
