Australian husband and wife writers Graeme Simsion and Anne Buist have teamed up to write a book together after very successful individual careers. Graeme is the author of the runaway hit The Rosie Project, its sequel The Rosie Effect, and another book The Best of Adam Sharp. Anne Buist is a psychiatrist, chair of Women's Mental Health at the University of Melbourne, and the author of the Natalie King psychological thriller series. The couple are great walkers, and it was while walking the Camino trail from Cluny in France to Santiago de Compostela in north-west Spain, that the idea for the book they've written together was conceived. Two Steps Forward is a feel-good story of late-blooming love, the movie rights for which have been bought by Ellen DeGeneres and publishing rights sold in a number of countries.
