Author Ernest Cline is offering readers of his new book Ready Player One the chance to win a Back To The Future-inspired DeLorean sports car.
The writer owns two of the fabled vehicles and he's giving one he purchased on auction website eBay.com away as part of a video game contest.
To celebrate the paperback release of Ready Player One, Cline has hidden a clue in hardcover and paperback editions of the book, which offers up details of a website that features ""three increasingly difficult video game challenges"".
The first fan to complete all three wins the car.
