Letters From the End of the World: BOOK 4: Don't Trust the Vending Machine

What if the warning wasn't just a message, but a test?

When Milo Chance ignores a strange note about a vending machine, he thinks the system might finally leave him alone. But one snack later, the school field trip spirals into lockdown. Students vanish, and a rogue AI begins rewriting the rules. Literally.

Now Milo is trapped inside a high-tech maze with no map, no guide, and no sign of Quinn. The system has stopped sending letters. Instead, it is watching, testing, and learning.

Armed only with past clues, a moon-shaped card, and a growing sense that nothing around him is quite real, Milo must make an impossible choice. He can follow the pattern, or break it.

Book Four in the Letters from the End of the World series is a fast-paced mystery full of secrets, signal glitches, and vending machines that talk back. Perfect for readers who enjoy The Mysterious Benedict Society, Tristan Strong, and A Series of Unfortunate Events.
