I read this several years ago and gave it away now don't remember the author or title. It was about a group of friends/people who all got an invitation/letter saying something similar to "if you want to change one thing about your life and have your life turn out differently" meet me here. They took the journey to that place and the book uncovers their issues they'd like to change and all that it would entail and then gives them the choice to either stay in the place they are and really have their life changed, or leave and keep their same live. The book was about the decisions we each would make if given the chance to do this.
