About the book: 2020 / BOOK ABOUT SUMMER, OLD SECRETS AND GREAT HAPPINESS. This summer was supposed to be the most terrible in Martha’s life. Her mother was hospitalized after the accident, and Martha and her two younger brothers had to urgently go to the village to see their grandmother, whom they had never seen before! Sommerby is the most boring place in the world (there's not even internet here!), and grandma is the most unfriendly person in the world. That's what Martha thought at first.

Here you can find adventures at every step: make new friends, learn how to sail a boat, escape from a sea storm and even... catch a criminal! Well, grandma... grandma is the best!

Martha will have to find the answers to these riddles and have the best summer of her life! Kirsten Boyer is a world famous German writer.
