Sang Sorenson's abusive mother is secure in a hospital, and her father has vanished to a new family of his own, leaving Sang and her sister to fend for themselves. Sang is hanging by a thread, and her only hope is a group of boys she feels she barely knows. She's never really alone. The Academy team has stepped in, promising to protect and care for Sang. Kota, Victor, Silas, Nathan, Gabriel, Luke and North take over, showing Sang they can be depended on for anything.

Sang Sorenson is forced to suffer through another of her mother's extreme punishments. It almost kills her. The Academy boys vow it will be the last. They're determined to keep Sang safe, especially from her own family. Their solution: complete invasion of her life. Kota, Luke, Silas, Nathan, Victor, Gabriel and North do everything within their power to show Sang what true loyalty means.

Sang Sorenson and the Academy boys return to Ashley Waters High School but before they get a chance to even settle in, Sang's life is threatened by an anonymous caller. They retreat to the protective walls of the Morgan estate, a safe house for when the boys are under fire. But when new threats can break through those barriers that once kept them secure, it leaves Kota, Victor, Silas, Nathan, Gabriel, Luke and North rushing to figure out who is hunting them.

The time has finally come for Sang Sorenson to be formally introduced to the Academy. Protocol dictates the boys keep the details of Sang's official introduction to the Academy a secret from her. The only thing they can advise her to do is to work on what will become her mantra: She is determined to stay with her team, no matter what. Despite her wishes, the boys are second-guessing her place with them, concerned for her safety. With dangers all around and threats closing in, some of the boys are questioning if this is the right time to bring her to meet the Academy at all.

Sang Sorenson struggles with her growing feelings when the Academy boys take her in and draw her closer into their world. They work together to uncover the true secrets happening at Ashley Waters High School, where Principal Hendricks will stop at nothing to take them all down. Adding to their complications, Nathan's father shows up, and he's just as ruthless and violent as ever, beating up on Nathan. Sang offers Nathan refuge in her home, but Marie is fed up with the boys.

It's been a week since Sang has attended any classes at Ashley Waters, and since then, everything has changed. Her school schedule has been turned upside down, and now, thanks to her absences, the school counselor, Ms. Wright, has suspended her. The fear of school officials getting further involved and looking to contact her parents has Sang and the boys forced into their best behavior. It seems that the once perfect student, Sang Sorenson, is now one of the school's worst, and without explanation, because she needs to keep her lips tightly sealed.

Sang Sorenson dreams of what life might be like for her in the Academy, but joining isn't as easy as simply writing an exam or passing an interview. She'll need to pull the team together to get them on her side in order for it to work, which is harder than it sounds. The boys will do anything to protect her, which, for some, means keeping her out. But that's not all that's going on in Sang's complicated life. After a shocking revelation, Gabriel Coleman splinters himself off from everyone, avoiding not just his Academy team, but even going so far as to avoid Sang.

Sang’s life was on pause after the dramatic break with her real family. Now she’s back in the game, returning to Ashley Waters to appear like a normal student. However, returning to school hasn’t made her life any easier. When it comes to the Academy and her role in the secret organization, there’s no such thing as normal. When Kota’s mother catches Sang and the guys in the complex web of lies they’ve woven, everything starts to unravel: Their relationships, their ties to the Academy. Everything’s under risk of exposure.

With an agoraphobic mother and a barely-there father, Sang abhors the isolation keeping her in the shadows. The only thing Sang craves is a fresh start and to be accepted as ordinary by her peers, because for her being different meant being cast out alone. When her family moves to a new school district, Sang infiltrates a group of boys nearly perfect in every way.

Sang Sorenson’s father abandoned her and her sister, leaving them to fend for themselves for months. He’s returned, and finds Sang is missing. He demands she return. Right now. Will he call the police if she doesn’t? Her Academy team doesn’t want to risk losing her ghost status and she doesn’t want to put them in danger, so she reluctantly returns home, but is comforted that she will still be monitored by them.
