Query: There has to be another one...

I was out of work this summer and read the entire series between July and September, couln't wait to get my hands on this one. I found the events and the characters darker in many ways than in the other volumes even though the wit and humor of the characters was familiar and warming. I hope the box of letters means that there will be another Outlander in the future...too much left unresolved for this to be the last.
