Proosakuiskaaja Oy offers editing and proofreading services for fiction and non-fiction books as well as audiobooks. We also offer a manuscript review service. Our company publishes writing guides through our subsidiary Penelope-kustannus. We have held a wide range of courses on topics such as working as a writer, the structure of a novel and writing short stories. We also run sparring groups where participants work on manuscripts either for their own publication or for submission to a publisher. The content of the courses is tailored to the wishes and needs of our customers.
