Amazing things happen in life. Eighth-graders Denis and Serhiy get on a real cargo ship during their summer vacation and go on a flight as "interns". Instead of returning home from Turkey immediately, the ship suddenly set sail for the Black, Azov, Marmara, Aegean, Ionian and Adriatic seas. This area and the surrounding shores, connected by these seas, were once called the Levant. And all the ports there still have something in common. The boys get used to the life and work of sailors, look for adventures on their own in Turkey, Russia, Greece and Italy, and sometimes find out from which the captain draws the appropriate organizational conclusions. But let's not be sad. Because adventures sometimes find even disciplined sailors. Are the guys ready for the test? Will they be able to return the ship to their home port in an emergency without the help of adults? Read this book.
