商品簡介
When 17-year-old Rowan Keller's older brother disappears under mysterious circumstances, she's told he was involved in illegal hacking activities. But when Rowan receives a cryptic message from his burner phone-sent after the date he supposedly vanished-she begins to dig deeper.
Her investigation leads her to a secret organization known only as "The Echo Protocol," a group that manipulates global events using predictive AI models and digital espionage. As Rowan uncovers layers of digital footprints, misdirection, and personal betrayal, she realizes she is being watched-and possibly used.
To find the truth, she must infiltrate the very organization that may have silenced her brother. But the closer she gets to the truth, the more she questions: Is her brother really missing-or did he become one of them?
