This is an automatically translated description

Serhii from Khmelnytskyi is thirteen. It seems that his whole life is marked by this unlucky number. The boy grows up without a father, does poorly at school, and on top of that, he doesn't know how to stand up for himself, which is readily used by his classmates. He thought so himself when a pet shop assistant gave him a box with someone who, she said, was to become the first friend in Sergiy's life. She didn't even warn him that this friend was a dragon! But that day, a journey begins, in which the dragon Viter will become not only his best friend, but also a kind of challenge. Because it depends on Serhiy whether the Wind can learn to breathe fire, fly, and finally grow up.
This book begins the series "Friendship that inspires" about an unusual friendship that connects worlds.
