Johan Edfeldt, a published children's book author and engineer, was born in 1984 in Lund Sweden, raised in Dalby and Åhus but now lives in Malmö with his wife and daughter. He has previously mostly written children's literature. But with "Polar", he takes a step towards a darker narrative. He works with business development within logistics in Denmark. Between the pages, he relaxes with barefoot running, chin-ups, and push-ups.
