What if the most impossible radio signal from space wasn't sent by aliens - but by your own future self?

Nineteen-year-old Zara Malik is the most junior intern at the Himalayan Deep-Space Radio Observatory, spending her nights monitoring cosmic background static. During a routine shift, she detects an anomaly on the 1420 MHz hydrogen line - a frequency that should not be transmitting from inside our solar system. The real impossibility, however, lies in the signal's structure: it is perfectly encoded with the wave pattern of a human neural oscillation.

When decoded, the message is in Zara's own voice, repeating the final secret words spoken by her late mother.

Zara soon uncovers the suppressed truth behind Project Antecedent - a classified framework proving that temporal transmission is possible through quantum entanglement and closed timelike curves. Hidden deep in the observatory's servers are thirty-one fragments of her own future consciousness. With a powerful defense contractor closing in to seize this reality-bending technology, Zara and fellow intern Kael have less than twenty-four hours to make an irreversible choice: bury the truth forever, or leak it to the world.

Grounded in real theoretical physics - quantum entanglement, causal loops, and neural oscillation research - The Last Signal is a mind-bending sci-fi novella that blends high-stakes corporate espionage with a deeply human story of grief, identity, and the terrifying question of who you are destined to become.

Perfect for fans of hard science fiction who want both intellectual depth and emotional resonance.
