'Opposites attract in this humorous illustrated graphic novel series about two best friends. Meet Gustav and Henri. This is their book. It's a bit about friendship and a lot about snacks. They love doing normal things together, like: • finding a lost shuttlecock – IN SPACE! • returning an overdue library book – 100 YEARS AGO! • or making cakes – IN THE BATH! You know, completely boring things. Join them for 100% of your recommended daily intake of adventures, escapades, and capers – all in one book!' (Publication summary)
