White Knights (Julie Moffett) Books in Order

The White Knights series is Julie Moffett's young adult spy mystery series, set in the same broad world as the Lexi Carmichael books. Its heroine is Angel Sinclair, a teenage hacker with an exceptional mind, a low tolerance for crowds, and little interest in fitting in. She attends Excalibur Academy, a school for technologically gifted students in Washington, D.C., where being brilliant does not make high school any less awkward.

At the beginning of White Knights, Angel is a loner. She is younger than most of her classmates, happiest with her computer, and still living with the unanswered question of what happened to her father, who disappeared when she was a baby. That personal mystery stays close to the series, even as Angel finds herself pulled into far larger problems.

Angel does not stay alone for long. Her friendships with outspoken Frankie and fellow tech-minded Wally form the heart of the books. Together, they have very different strengths and personalities, but they learn to trust one another when school life intersects with hacking, government attention, and genuine danger. The White Knights name fits their growing role as a team that wants to do the right thing, even when the adults are keeping secrets.

Smart kids get a chance to do more than sit quietly in class.

The first book brings Angel into a mystery involving a dangerous hacker and the people around her school. It also introduces crossover characters and agencies familiar to Lexi Carmichael readers, without requiring knowledge of the adult series. Angel's talent with computers is real, but the stories do not treat technical skill as a magic solution. She has to learn how to work with others, take risks, and cope when a situation cannot be controlled from behind a screen.

In Knight Moves, Angel, Frankie, and Wally are invited to compete for a place at a secret government training program for future operatives. The setting shifts from a tech-focused high school to a demanding spy-school tryout, where physical challenges and teamwork matter as much as raw intelligence. Competition raises the pressure, while Angel's missing father remains an urgent part of the larger story.

One-Knight Stand takes Angel further into training and danger as threats against her family force her to act. The tone throughout is quick, clean, and upbeat, with mystery, espionage, friendship, and plenty of geeky problem-solving. Start with White Knights for the full picture, then continue in order to see Angel grow from a guarded young hacker into someone ready to lead.
