Just a hundred yards off the shores of Helsinki, beyond its embassies and marina, its cafes and upscale homes, lies Harakka Island. There is no bridge to Harakka; it must be reached by boat — or by trudging over an ice sheet, when the temperatures plummet in the winter. There are no cars, no bikes and no electric scooters on the island. Even dogs aren’t allowed. But it’s a haven for a thriving community of artists. The acclaimed children’s book illustrator and author Marika Maijala is one such artist. And it turns out the island is still a place of transformation and discovery. Her studio on Harakka, part of the island’s Artists’ House, is where she wrote and illustrated “Rosie Runs,” which will be published in the U.S. by Elsewhere Editions.
