"Opposing Forces" presents itself as an alternative to overcoming the great duality that exists in each one of us. How many times in life are we faced with situations in which both alternatives have favorable and unfavorable circumstances and the act of choosing one of them becomes true martyrdom. We must learn to reflect and think carefully about which the true path to be followed is and the consequences of that choice. Finally, we need to assemble the "opposing forces" of our lives and make them bear fruit. Thus, we can achieve a much-desired happiness. As for the aspect of the book, we can say that it came from a cry that I heard in the cave of despair. This cry was the cause of all the adventures told in the book. Mission accomplished; I hope I have reached my goal which is to make just one person dream. This is what I propose even more now since we live in a world full of violence, cruelty, and injustice. The "opposing forces" never again will be the same after its publication and I cannot wait to start a new adventure together with readers who also intend to do so.
