I also use Family Historian, which I have used for a number of years now. It is very good for web publishing but just slightly more difficult if you are wanting to produce a printed book. However with a (younger) sister and (even younger) neice who refuse to embrace modern technology I am left with no option but to produce word documents for them.
The way I do this is to ultilise MS Word, making up my own frontispiece and title pages. Using the Reports facility on Family Historian I obtain the type of report I want (Ancestor, Descendant, Individual) and save this in a .rtf format for word processing. This I can then edit by adding, deleting or amending information and then pasting the final version into my Word book. For family trees using the Diagram tool on Family Historian I save the relevant family tree as a .jpeg (although there are a number of different formats you can save the diagram as) and then use photo editing software to keep the size of the tree manageable, and therefore readable, and then insert this into my Word book. If necessary I then add addition images (photos; censuses; birth, marriage and death certificates).
To finalise I laminate the first and last pages of the printed book to give it a bit of strength and "bind" together by using a plastic strip to hold all the pages together.
PS - If anyone else using Family Historian knows of a simpler method ...........
