An Israeli physicist accidentally texts his girlfriend through a time machine. Four years later, he discovers that text is the only reason she's alive - and now he has to choose between her and 12,000 strangers.
Then the news changes. A headline you remember is different. A bus crash that killed 14 people... didn't happen.
Your text saved them. 160 characters. Six-month range. 72-hour recharge.
The Mossad finds out. They want you. Now you're saving spies, stopping bombings, and rewriting the Middle East one SMS at a time.
But here's the thing they don't tell you about time travel:
Your girlfriend? She died in a car crash in 2019. The text you accidentally sent? It buzzed her phone 16 minutes before the collision. She pulled over. She lived.
She's not your girlfriend. She's a ripple.
Undo the timeline, she's gone. Keep the timeline, 12,000 people die.
And you're the only one who can press send.
