Wrapping up The 5th Wave (continued)

            But when the group of graduates who have discovered the secret are heading back to rescue the last member, Cassie is told by the silencer, who is in love with her, that they were training the children to become the 5th wave and she remembers that her brother Sammie is in the Air force base and is going to go after him. She pretends to act younger than she is and gets into the base and has to knock out some of the doctors who were going to run the Wonderland test on her. The Wonderland test allows them to see all of your memories and everything that has ever happened to you. She realizes that if they get into her head they will realize why she is there and will immediately kill her.

        While she is breaking in the group of graduates originally from the base are also going for Sammie, remembering him as the youngest in their group. After a chapter of explaining how they broke into the base and how they get to Sammie, they get caught. Caught by the commander of the base,  Colonel Vosch, who knows all about them. While captured they are going to torture Sammie to figure out how they got in and who is helping them because Cassie would've actually been caught but the silencer that is in love with her takes both of them down. Right when he is about to kill Sammie the power goes down and Vosch goes to see what happened. Next the silencer comes and saves them and they get away from the base safely but he loses his life manually setting off the explosive in the air force base. And that's where it ends.
