Matias, Doctor Einstein and The Time Machine
(Matías, el doctor Einstein y la máquina del tiempo)

Matías is about to discover that an elevator is not just an elevator. When Centella, his inseparable ferret buddy, pushes the button to go to Aunt Enriqueta’s apartment, the elevator turns into a time machine that takes them straight to Albert Einstein’s dining room, in Berlin, on October 28, 1915. There they will meet Einstein himself.

My name is Matías, I’m 7 years old and I have a pet ferret named Centella. This is the story of my adventures in time travel.
