Ever wonder why people write ? Especially fiction ? Me too. There are many different types of writing of course, but fiction (all kinds, sci-fi, etc), releases all the pent-up imagination of the author. It allows him/her to create new worlds that no one has ever seen. The creation of a new experience beyond imagination perhaps, or in depth on some particular exploration he/she has ion mind.
Hopefully, done right, it becomes a good read and everyone enjoys the journey !
