I haven't used Personal Historian but most family tree software will produce a narrative report. By it's nature any such program will tend to be very repetitive, just changing names, dates, places, etc.
I found the only way to produce something readable is to write it yourself; you can always include charts, etc. to illustrate the text. I use PagePlus desktop publishing software which allows you to place photos, charts & tables in the layout, play around with different fonts and move things around to best effect.
I notice there is a free 30-day trial download for Personal Historian . . . maybe that's the way to go to see if you like it.
