Now a complete 5-book series.
There was never a signal. Only a whisper. Not meant for us.
Commander Elara Myles vanished beneath Triton's ice while chasing a mysterious anomaly. Her final transmission didn't call for help-it warned of something ancient. Something waiting. Not a message, but a key. And Earth was never supposed to find it.
Now, a rogue crew defies orders and follows the signal to Kepler-22b, a planet cloaked in silence and secrets. What they discover isn't a beacon. It's a system-vast, intelligent, and already listening.
Threshold Signal is the gripping first book in The Threshold Sequence, a cerebral, atmospheric sci-fi saga exploring alien logic, rogue explorers, and the consequences of unintended contact.
We weren't the message.
We were the keyhole.
And something just turned it.
