When someone purchases a copy of the book, I ask them to share someone they would like to donate a copy of the book in honor of or in memory of. Donated books will have a bookplate in the front that notes for whom the book is given in honor or in memory.
Why you are sharing your book–your story–with others is your “why story” or your platform. And, it needs to be front and center when you write, speak, blog, video, have a conversation with a friend, share a book out of the trunk of your car. How would you describe your “why story”?
