I would recommend putting together a proposal which would include table of contents, a couple of chapters, description of audience and how this book is similar and different from others who have done well. Then I would start looking for agents and be prepared for lots of rejections and lots of editing after that! Publishing world is pretty difficult, but I trust she knows something difficulties!
