The author died last year after a battle with cancer
Two new novels by Jurassic Park author Michael Crichton have been scheduled for posthumous release, his publisher has said.
HarperCollins said the author left behind a host of electronic files, from which the two new novels are taken.
Pirate Latitudes, an adventure set in 17th Century Jamaica, will be published in November. A second currently unfinished novel will come out in 2010.
The author died last November of cancer aged 66.
Publisher Jonathan Burnham told the New York Times that the novel was "eminently and deeply and thoroughly researched".
"It's packed through with great detail about navigation and how pirates operated, and links between the New World and the Caribbean and Spain," he said.
HarperCollins said it was looking for a co-writer to complete the second novel - a technological thriller, currently untitled, of which Crichton had written a third before he died.
As well as Jurassic Park, Crichton also penned books like Congo and Disclosure, all of which were adapted into films.
His books have sold more than 150 million copies worldwide and he also created the long-running US hospital TV drama ER, which ended its run after 15 years earlier this month.
