The Factory #3
Undisclosed
An undercover spy seizes the spotlight to avoid exposure in the gripping third installment of Aya de León’s award-winning Factory series.
Teen spy Amani Kendall’s first solo mission seems straightforward: to befriend Danielle, the angry, grieving daughter of a former Factory operative, and prevent her from blowing an agent’s cover and exposing the Factory—an international organization of spies safeguarding people of color—to the world. But in order to get close, Amani will have to step onstage and win a place in Danielle’s band and at the elite summer camp hosting the “Next Teen Sensation” competition. Meanwhile, the band's charming bassist falls head over heels for Amani, who is not sure whether to be flattered or overwhelmed. Add in an increasingly volatile Danielle, a nefarious billionaire sponsor, the pandemonium that surrounds a K-pop supergroup, and an industry that thrives on fatphobia and racism, and it will take all of Amani’s wits and spycraft to keep her mission on track. In a riveting companion book to Undercover Latina and Untraceable, a seasoned suspense writer explores the intersection of the personal and the political with rapid-fire intrigue.

Amani’s first mission by herself and it seems straight forward, just keep another operatives kid who just lost her dad to a mission not to blow the other operative on the mission’s cover, and the Factory as well. Amani knows what will happen if she doesn’t succeed and really doesn’t want that for this kid or any kid. In order to get close Amani must sing on a stage and win a place in Danielle’s band and move on to the summer camp with them for a place in a show The Next Teen Sensation. Amani must keep her cover through everything and still try and win the trust of Danielle and help see why she should help keep what she knows a secret.
I love this series with the strong female characters. There is some action, a lot of suspense, and tons of fun. Amani faces a lot of the pressures of teen life and it shows great ways on how to deal with it. The plot and series are refreshing to read it is not the same as other books and I really like the characters all of them, and hope to see Amani again.

This is a sequel to Untraceable, and follows Amani as she goes undercover in a music school to help the daughter of another Factory agent whose actions might constitute a security breech. There is some drinking; this reads more like YA than MG. Lot of good spy activity and social justice connections.

A more condensed version of this review originally appeared in the article "19 YA Series That Are Bursting with Emotion" for School Library Journal:
Fifteen-year-old Amani Kendall has her first assignment as a lead operative in her latest mission. With support from her operative parents, Amani has to get close to Danielle to protect the covert organization known as The Factory and its work to support people of color.
Joining Danielle's band at an elite music camp, Amani has to stop Danielle from revealing the existence of the agency while processing grief over her father's death. Something that becomes increasingly difficult as Danielle tries to use her song writing to process her grief and anger.
Amani needs to get Danielle to therapy before The Factory has to force Danielle to go off grid for everyone's protection in Undisclosed (2025) by Aya de León.

Undisclosed is de Leon's third book about the Factory and its teen operatives. The series starts with Undercover Latina and Untraceable which is a prequel novel explaining how Amani first learned about her parents' roles within the organization. Amani has help in this installment from her best friend (and the protagonist of book one) Andréa as they navigate spycraft and band dynamics.
Amani is Black, plus size, and confident in her own skin even if she is aware not everyone else is as comfortable with her taking up space. During the band camp she ably navigates rampant racism and fatphobia from industry professionals while completing her assignment. At the same time she faces ethical qualms from befriending Danielle while trying to silence her revelations about the Factory and also content with excessively amorous attentions from a fellow band member--something she isn't used to receiving and isn't sure she wants at this stage.
Undisclosed is an action-packed blend of spies and music where friendship is the ultimate weapon in a spy's toolkit; slow pacing is the only wrong note in this bopping body positive adventure.
