Orchard Books has promoted Jessica Clarke to fiction editorial director, reporting to publishing director Megan Larkin.
Clarke succeeds Rebecca Frazer, who is returning to her native New York.
Larking said: “Jess has been an outstanding member of the team since joining Orchard Books from Random House, working across the list on our hugely successful young series, Secret Kingdom, as well as looking after top authors like Jonathan Meres.
"She has also brought in some wonderful new talent, and we look forward to exciting times for the Orchard Books fiction list under her guidance.”
Orchard has also appointed Grahame Lyas as senior designer, picture books and brands, reporting to art director Sophie Stericker.
