The story, 'Mortal Kiss', will be serialised in small chunks daily from today until Halloween (31 October).
The four main characters will have Stardoll profiles and the membership of the site will be encouraged to vote on plot points and take part in writing contests based on themes from the story.
They will also be able to buy items associated with the story to decorate their own profiles, in line with Stardoll's established practice of selling virtual goods.
'Mortal Kiss' is a paranormal mystery created in collaboration between writers and editors at Random House Children's Books and artists and programmers at Stardoll.
The story will be told through an interactive book and map of Winter Mill, a fictitious town in New England.
The collaboration has, according to Stardoll UK general manager Chris Seth, evolved out of the website's multi-year relationship with the book publisher as an advertiser and brand partner.
Seth was coy on the financial details of the partnership, declining to confirm whether Random House is getting a share of the revenue from the sale of virtual goods or advertising around 'Mortal Kiss'.
He said he saw the project as a chance to investigate the potential of charging for content as well as licensing original property.
There is a potential global market for 'Mortal Kiss products'. Stardoll claims to have more than 100 million registered users worldwide and is making synopses of 'Mortal Kiss' available in 17 different languages.
