So, this book throws you right into the action. We meet our main character, a historian named Leo, who's pretty down on his luck. While researching a dusty old family legend, he finds this strange object—the Oracle. At first, he thinks it's just a cool historical trinket. But then he accidentally activates it and gets a front-row seat to a major event from 200 years ago. That's when things get crazy.

The Story

Leo quickly realizes the Oracle doesn't just show the past; it can reveal secrets in the present and glimpses of possible futures. He starts using it, trying to correct small personal mistakes and even prevent historical tragedies. But every change, no matter how well-intentioned, has massive, unintended consequences in his own time. The book becomes a race as Leo tries to understand the Oracle's rules before his own timeline unravels completely.

Why You Should Read It

What I loved was how personal it felt. Leo isn't a superhero; he's a guy who makes a huge mistake and then has to live with it. His struggle isn't with villains, but with his own conscience and the butterfly effect of his actions. Serrano makes you think: if you could go back and stop one bad thing, would you? Even if it meant erasing something good that came from it?

Final Verdict

This is perfect for anyone who loves a good philosophical puzzle wrapped in a page-turning story. If you enjoyed the 'what if?' tension of shows like Dark or the personal stakes in books like The Midnight Library, you'll devour this. It's a brainy thriller that sticks with you long after the last page.
