About this eBook
This original, interactive thriller from debut author Jay Martel follows a brilliant teenage girl as she races across D.C. to decode the clues her father left behind, which may just be the key to saving the country from a devastating tragedy.
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.
With the same agents now hot on their trail, Mia and Logan must navigate their way through American history’s most iconic sites and uncover its most well-hidden secrets to reveal the truth about her family and stop a deadly attack.
In this non-stop thrill ride, the reader has the chance to test their own codebreaking skills alongside Mia, lending an exciting interactive element to this page-turning thriller packed with action, romance, and life-changing revelations.

I found Codebreaker to be an intriguing tale. I liked Mia who is smart & has a knack for solving codes. I liked the different codes featured in the story & that a brief history of each one was provided. The mystery had twists & turns. Minor foul language. It may be listed as YA, but I enjoyed it. I was surprised that this is the author's debut novel. I enjoyed this compelling tale!
