A signal flickers into existence for exactly seven seconds-then vanishes.
It appears again two days later. Same duration. Same precision. Same silence.
When Earth's sensors detect the anomaly, it's quietly routed through the Delta Directive, a classified safeguard for threats that must be handled without attention, attribution, or delay.
It appears again two days later. Same duration. Same precision. Same silence.
When Earth's sensors detect the anomaly, it's quietly routed through the Delta Directive, a classified safeguard for threats that must be handled without attention, attribution, or delay.
Richard and his cadet team are assigned their first Delta mission aboard Specter One, a stealth vessel designed for operations that officially do not exist. Their investigation reveals a cloaked courier ship, a coded transmission, and a criminal operation built on leverage rather than force.
At the heart of the plot is Dax Timberly, an engineer whose small compromises have grown into dangerous coercion-putting his family, his work, and planetary security at risk. When Dax chooses to tell the truth, the cadets must decide what matters most: chasing a larger, unseen enemy or rescuing the man who tried to make things right.
