De Luca is an advocate for the Shetland dialect, travelling internationally to share her native dialect with similar linguistic cultures, like Scandinavia and Iceland. De Luca is a co-founder of Hansel Co-operative Press, a non-profit cooperative, which promotes literary and artistic work in Shetland and Orkney.
De Luca has focused on promoting her native language through work with Shetland children. She has written children's stories in the Shetland dialect. De Luca translated Roald Dahl’s George’s Marvellous Medicine into Shetland dialect as Dodie’s Phenomenal Pheesic (Black and White Publishing, 2008). Also published in 2016 by Black and White Publishing are two Julia Donaldson books, translated by De Luca: Da Trow (The Troll) and The Shetland Gruffalo's Bairn, (The Gruffalo's Child).
