Graeme Simsion's debut novel, "The Rosie Project," is being touted as a best seller even before it has been published and the author has already received $1.82 million in advance.

Movie producers and international publishers are lining up to sign Graeme Simsion's debut novel, "The Rosie Project." The book has been snatched up by 34 publishers in different countries. As the story of the book is a comical take on a disability, publishers reckon the book may not be an instant hit. However, they are of the opinion that the strong characters of the book may challenge perceptions of people with the disorder.

"The Rosie Project" tells the story of a man with undiagnosed Asperger's syndrome. The man, Don Tillman, decides to look for a wife drawing up a "scientifically valid" questionnaire to assist his quest for the perfect woman. Tillman is a professor and while giving lectures on Asperger's isn't aware that he shows signs of the same symptoms himself.

The novel is reportedly a mix of "One Day" by David Nicholls, which is a bittersweet love story and Mark Haddon's "The Curious Incident of the Dog in the Night-Time," which is about a teenager with Asperger's.

Simsion revealed to the Observer that until now, he wasn't sure that he had the capability to write a novel. However, the $1.82 Million (approximately) advance from his debut novel has given him the opportunity to become a full time writer.

Publishing house Penguin will be releasing the book this May and the author will fly down to the U.K. for pre-release events. The publishing house's Sam Humphreys revealed that she was determined to out beat all rivals to gain publishing rights for the book as she was hooked on to the novel right from its first page.
