@sesasaki First of all, sorry I'm replying so late.
Well about the Satisfaction, I was satisfied with the ending to some extent, like Dr. Al-Fadi's return and the discovery of the cure, but I would still like to read more of Bud and Grace 'situation'. And as far as the little cliffhanger in the epilogue is concerned, who can be satisfied without reading more of the story.
Though my real hunger which needs to be satisfied is for literature, which only people like you can do with your efficient writing and incredible imagination.
Honestly, I've become a very big fan of yours in the short period of the past couple of months and I hope you keep up your excellent work cause I definitely would keep on reading it!
