: A girl living at the end of the 21st century falls into adventure on Earth and Mars; saves a whole civilization by moving to the distant past, and fights with space pirates in deep space.

All three stories are narrated on behalf of Alisa Selezneva’s father, a professor of cosmobiology.

A girl with whom nothing will happen

Alice Selezneva had the ability to "disappear at the most inopportune time" and make discoveries that turned out to be "beyond the power of the greatest scientists of our time." Her dad, a cosmobiologist, Professor Seleznev, confident that at the end of the 21st century nothing would happen to his little daughter, wrote down several stories that happened to her.

Thanks to Alice, the Martians learned who Baba Yaga is. The girl made friends with a brontosaurus and figured out how to cure him. Accidentally lost on Mars, Alice found the structure of an ancient Martian civilization. The beast brought from a distant planet and presented to the girl turned out to be reasonable.

Having moved to the country in the summer, Alice saved a scientist who had unsuccessfully tested her invention. Then the girl found guests with a distant star, who turned out to be tiny little men. On a test of a time machine, Alice fell into the past and met a famous science fiction writer.

Alice's Birthday

To make Alice Selezneva a birthday present, the girl’s friend, alien and famous archaeologist Gromozeka took her to explore the recently discovered planet Koleida. All living things on the planet died out due to the space plague, the virus of which brought to Koleida the first spaceship launched from it. It turned out that Gromozeka took Alice with him with the intention of sending the girl to the past so that she would try to save life on the planet.

Together with her new friend, a kitten-like archaeologist Rrrr, Alice went back in time, made her way to the cosmodrome and sprayed the astronauts with a liquid vaccine against the cosmic plague. Returning in due time, Alice and Rrrr learned that they had succeeded, the civilization on Coleida was saved, and the locals did not even suspect that someone had saved them.

Alice's Journey

Cosmobiologist Professor Seleznev took his daughter Alice on a space expedition to collect rare animals for the Moscow zoo. At the beginning of the flight, the girl learned about the Three captains, brave explorers of deep space, and then the semi-intelligent talker bird belonging to one of the captains came to the Seleznevs.

Govorun led an expedition to an unknown planet where space pirates held the Second Captain in captivity, trying to learn from him the formula of absolute fuel. This formula was given to the captain by the inhabitants of the neighboring galaxy, where he recently visited.

With the help of the talker, Alice managed to get out of the dungeon, where the expedition members appeared together with the captain and brought help.Space pirates were arrested, after which Alice asked the captains to take her with them to a neighboring galaxy.
