Johan Rundberg: the August Prize-winning Swedish author of the Moonwind Mysteries — atmospheric, genuinely dark Nordic-noir crime set in 1880 Stockholm, for confident older readers who want a mystery with real weight.

Johan Rundberg is a Swedish author, based in Stockholm, who writes across picture books, early readers and middle grade. He is best known internationally for the Moonwind Mysteries, a Nordic-noir crime series set in the frozen, poverty-stricken Stockholm of 1880 and following Mika, a sharp-eyed orphan girl recruited by a detective to help hunt killers through the city's cruellest streets. The series opener, The Night Raven, won Sweden's prestigious August Prize in the children's and young-adult category. Translated into English by A. A. Prime and Eva Apelqvist, the books are atmospheric, genuinely dark historical thrillers — unflinching about hardship, cruelty and death, yet warmed by Mika's grit and an unlikely found family. Serious, propulsive mystery for confident older readers ready for a proper thriller with real weight.
