Just finished reading the story and it was great. But please, please be working on a sequel. You just left too many threads hanging to not do a sequel. If you don't do a sequel just know that it is likely to cause me sleepless nights trying to decide what might happen next. Is it working. The guilt - trying to get a sequel. Pretty, pretty please.
This is your muse coming to bash you over the head with more great ideas for the continuation of the story. They will be delivered with such force you just have to continue.
