Alice Seleznyova. A Hundred Years Ahead

Kolia is an ordinary schoolboy from Moscow. His neighbor is taken to the hospital by an ambulance, and Kolia promises to keep an eye on the apartment, but suddenly discovers a time machine in an unlocked room. Kolia initiates a self-launch into the future, brilliantly flipping in the starry interplanetary space. He selflessly saves an important device that is being hunted by space pirates. Alice (a guest from the future), having taken a myelophone from her father, travels to the past and tries to find Kolia.
