Vook’s team of experts can design, create, sell and help market your ebooks. Whether you want to add multimedia elements such as video, carefully style text, or launch a catalog of titles, we’ll make your ebooks look exceptional. At Vook, you can always talk to a human—we price each project with a custom quote.
We don’t just convert manuscripts; we style and enhance ebooks to tell compelling stories that might not have been possible in print. We’re proud of the titles we’ve helped share with the world and the mark we’re leaving on the ePublishing landscape.
