The Grace Crasher Sequel

Ok, it’s official! I’m going to put aside my 30k-40k word manuscript (not related to The Grace Crasher) and work on a sequel or companion book to TGC. I know the basic subject and themes I want to write about. I could weave those things into a story about Mark and Julia with relationship problems set a few years after TGC OR Tori and her new husband with relationship problems. (I feel bad giving M and J more problems though! But no problems=no story.)
