Vunderverse

What would you do if a real star fell into your cup of hot chocolate one day? What if all the formulas in your math textbook suddenly started dancing? And what if it turned out that you were the one responsible for saving all the wonders in the world?

Ten-year-old Lily always knew that beyond the ordinary world existed the Vunderverse - a universe far more magical than adults could imagine. She could see rainbows even on the cloudiest days and find constellations in the spots on an old globe. But even she wasn't prepared for what would happen that morning when an ordinary wall in her room melted like cotton candy, revealing the path to Aunt Alice's laboratory - the only place in the universe where science and magic drink tea together.

Now Lily must:

- Save the last colors of the world from the Grey Calculators

- Teach the multiplication table to sing

- Help a shy telescope that's afraid of being tickled

- And discover a secret that could change everything we've come to believe in

But most importantly - she must do it all before the last star forgets how to shine and the last ray of sunlight unlearns how to dance.

"The Mystery of the Vanished Rainbow" is a story about what happens when quantum physics meets fairy tales, and probability theory learns to believe in the impossible. This book is for everyone who has ever wondered: what if wonders exist not in spite of the laws of science, but because of them?

Prepare your cup of hot chocolate and check - maybe there's already a tiny star floating in it, ready to change your life forever?

Because sometimes the most important discoveries begin not with formulas, but with believing that behind the last page of a mathematics textbook really does hide a map to the island of lost wonders...

And what if this book isn't just a story? What if it's a door?
