Four years after winning the 2010 Muskoka Novel Marathon in Huntsville, Ontario, Toronto writer Amy Stuart has signed a two-book deal with Simon & Schuster Canada.

During the 72-hour charity event, Stuart completed 50 pages of a story about a woman fleeing an abusive husband who is forced to investigate the disappearance of another woman. After winning the fiction award, Stuart continued working on the novel as part of her MFA in creative writing at the University of British Columbia and signed with literary agent Chris Bucci of Anne McDermid & Associates.

In an interview with the Huntsville Forester, Stuart says, “Where other parts of the book have changed and shifted a lot, the general gist of the [pages written during the marathon] is still the same.”

The untitled novel is scheduled for May 2015.

This year’s Muskoka Novel Marathon will be held July 11–14 in Huntsville.
