Codebreaker

Mia Hayes has peaceful plans for the summer—find a part-time job at a coffee shop and work on her college applications. Those plans are shattered one night when government agents arrive unannounced at her home seeking something they believe her father has taken. When the dust settles, her mother is dead and her father is gone, a fugitive on the run.Three weeks later, and still reeling from her father’s betrayal, Mia spends her seventeenth birthday at a protest in the heart of D.C., where she meets Logan, a rebellious and charming hacker. Just as she’s enjoying her first happy moment since the night her world exploded, a voicemail from her father arrives to upend everything she believed about her family, her past, and what really happened that night three weeks ago. Even more, the voicemail hides another encoded message inside which, once Mia solves it, sets her and Logan off on a mission from her sleepy suburb straight into the heart of the federal government.
