Frozen Hell is the first enhanced book to describe the dramatic early battles of the Second World War between the Soviet Union and Finland in the winter of 1939–1940. Based on a Finnish bestseller, the unique interactive book includes stunning photographs and film material that demonstrate how the small nation of Finland overcame an enemy many times bigger in unbearably cold conditions.

The very easy-to-use enhanced e-book application is based on a Finnish bestseller, and the text has been translated into English directly from the contents of the original. To support the reading experience, the enhanced version adds dramatic photographs, authentic film material, detailed maps describing the course of the fighting and much more to bring the events of the Battle of Raate Road to life as never before. The app provides a step-by-step account of the fighting with a wealth of information about events during the battle and its aftermath.

"Frozen Hell is an impressive experience even for those who might not be highly interested in military history. The readers get to see video material not shown in public since 1940, and the authentic pictures and other features help realise the conditions the soldiers had to endure," Mika Koivula, Director from Gummerus Digital says.

Digia's excellence in digital publishing

Together with Gummerrus and an advertising agency, Digia helped translating the original book content to a digital form for the Apple's iPad platform.

"For us, the project was to solve typical issues for usability and end user experience in the iPad / iOS environment," says Harri Halminen from Digia. "We helped to modify the orginal pdf material so that the software libraries offered by the platform can use the content without compromising the user experience."
