Hi, I've been wondering whether it would be possible when my story is eventually published if it would be possible to have multiple endings published in the last installment of the series. What I mean by this is I want to know if the writing could be changed subtly throughout the last couple of installments to fit different endings. I have 3 - 4 different endings planned but I don't want to decide which one to use like most other books do. Would it be possible to have it to where one bookstore would carry one "strain" (for lack of a better word) and another have a different strain? Each strain would have a different ending, but no way to differentiate which ending it is until the reader finishes the last book. I mostly want to know if this could be possible because I want the readers to argue with each other about which of the endings is a "true" ending.
