My debut novel Kugghjulssjälar (Cogwheel Souls) was published in March 2025. It's a dark techno-fantasy for adults, set in an alternate world that's both like and unlike our own. It's part of a loosely connected series; each installation has different characters and can be read on its own.

Awais Aftab read the English version, and interviewed me about it here: Cogwheel Souls: Q&A with Sofia Jeppsson on Madness, Fantasy and Philosophy 

Your body is not you. Your body is nothing but flesh, nothing but cogs and wheels and springs. Only your soul is you. You must always prioritise your soul.

Lovisa Lagerqvist is going to be a protector and save ordinary people from hostiles – or demons, as they say in church. It’s dangerous and painful and may cost you both blood and body parts, but none of that matters as long as your soul remains whole. Doesn’t matter as long as you've got booze and drugs, prayers and mantras, sex and social media for distraction. Remember, everything can be replaced! Flesh and bones or plastic and steel doesn’t matter when it’s nothing but cogs and wheels anyway. But the hostile called Skinmask becomes increasingly strong and multitudinous, and it/they want to drill a hole in Lovisa’s head. Sharp tools straight in the brain.

Your brain i not you. Your brain is nothing but flesh, nothing but cogs and wheels and springs. Everything can be replaced.

Det Nya Köttet (translates to either The New Flesh or The New Meat) is a short story published as a separate little book. It's a prequel set roughly ten thousand years before Coghweel Souls, in a late ice-age environment.
