Like it says in the title...
The submission portal, www.harpervoyagersubmissions.com, is now open and will be until the 14th of October 2012. The manuscripts will then be read and those most suited to the global Harper Voyager list will be selected jointly by editors in the USA, UK and Australia. Accepted submissions will benefit from the full publishing process: accepted manuscripts will be edited; and the finished titles will receive online marketing and sales support in World English markets.
Voyager is seeking an array of adult and young adult speculative fiction for digital publication, but particularly novels written in the epic fantasy, science fiction, urban fantasy, horror, dystopia and supernatural genres.
