No matter the genre, the writer's challenge is to not only pen believable stories, but the tales told must leach into the reader’s soul. Punch them in the gut. Tear at their hearts. Evoke indignation at injustice or fill one with satisfaction when justice is served. Elicit tears of sadness or joy in empathy for the character. Build tension then scare the crap out of them. That is achieved through skilful writing. Proven by our litmus test–our readers.
