Kilorn agrees to help Mare find Cal and they enter Barracks 1 through a moon pool under the surface of the ocean. The Colonel denies the request and leaves, and Farley gives Mare the key to Barracks 1. She tells him that Mare wants to find other newbloods with the aid of “the list” – a notebook of names given to Mare by Silver-blooded Julian Jacos. As she talks to him and Farley, the Colonel enters and strips Farley of her command. Determined to find Cal, Mare goes to see Shade in the infirmary. They have joined the Scarlet Guard to overthrow Maven and are keeping Cal in the seemingly non-existent Barracks 1. The next day, Gisa tells Mare that the man with the bloody eye and his soldiers are from Lakeland, a country warring with Norta to the North. She has a tense reunion with her mother, father, brother Tramy, and sister Gisa. A man with a bloody eye and an unfamiliar uniform takes Cal and imprisons him, and Mare goes to the bunkers to find her family. Mare arrives on Tuck and is greeted by another of her brothers, Bree. They narrowly escape to a submarine, called a Mersive, and they depart for a remote island called Tuck. Mare realizes that the Scarlet Guard is much more extensive than she had assumed.

They fight against Maven and a Silver army in the ruined city.

Mare’s brother Shade, another “newblood” with the power to teleport, and her childhood friend Kilorn accompany them. They ride on an underground train to Naercey with Captain Diana Farley and her team of Scarlet Guardsmen, an underground Red resistance. Mare Barrow-a Red with the Silver ability to control electricity-and Tiberius Calore-the exiled prince and rightful heir to the throne-have just escaped imprisonment by Maven, the new king. The kingdom of Norta is divided between Red bloods, the downtrodden lower class, and Silvers, the power-hungry royalty with superhuman abilities.
