Masks of Nyarlathotep
Harriet is 31 and has left a string of failed relationships behind as she focussed on her career and finding answers to some questions that maybe should never be answered. While she has been a bad girlfriend/wife she is very likable and therefore still on good terms with all her exes and her long suffering boyfriend Tim.
She has two kids, who she cares deeply about but knows (due to having a reasonable amount of insight into herself) are actually better off with their father so the custody arragement favours him, but is very friendly.
Recently Harriet has began to consider her time numbered as the answers she is finding become stranger and stranger and she has began preparing for her own death.
