Helga Köller – Translator

EN→DE book translator. 16 titles for traditional publishers. Thriller/Crime & biographies. For publishers & quality-focused indies.

Overview

Hello! I’m Helga — a professional English → German translator and German-language editor specializing in fiction, especially thrillers, crime (including cosy mystery), psychological suspense, and biographies.

My goal is to deliver a German text that reads like an original: natural, fluent, and true to the author’s voice — with strong pacing, tone, and emotional impact.

📚 Published translations include work for traditional publishers such as Festa and Eulenspiegel/Neues Leben.

✨ What I offer

• Full book translation (English → German)

• Careful adaptation of voice, tension, humor & emotion

• Consistent terminology and character voice across series

• Reliable communication and on-time delivery

🤝 I work with both publishers and independent authors who care about quality and professional standards.

⚠️ About AI / MTPE

I primarily provide human translation. MTPE is possible only after reviewing the manuscript and the draft, and only if the raw output is of professional quality.

I’m happy to provide a short sample translation (1–2 pages) to confirm tone and fit.
