This book is a children's picture book, landscape layout, and the first book in the series. This book is in forty languages. The story is about a small Martian animal, called a Feelup, which looks like an Earth cat. Her name is Kuro. She got abandoned in space, and her spaceship is damaged. She is very sad, as she lost her best friend in space, and now she is all alone. She crash lands in Australia, and finds a small boy named John. He has run away from home, because his sister is sick and he believes that if he leaves home his parents will have enough money for a doctor to help sister get better. Kuro convinces John to show them how to get to his home. She becomes his friend. John's sister is very sick, but Captain Kuro has special magic abilities. She shows John how to heal his sister. To the amazement of John's parents and doctor the sister gets totally well. Kuro can of course also speak in quiet-talk, and can listen to people's and animal's thoughts. So, she shows John how to do this too. John's mother is skeptical about what John says Kuro can do, as after all, Kuro is only just a cat, right? John's father on the other hand, is not totally sure, as Kuro did bring John home, and his daughter is now well. He then asks Kuro if she will stay with them as she needs a home too. So Kuro is now no longer alone.
