crutledge, thank you much for Sweeny Todd. But,it has a few things that I hope you will see to fixing.
The first is that em dahses have been converted to dashes. Thi sis easily fixed by installing the Book Cleaner files over at

The second that I've noticed is that you are using the default style of bold for the base font. This is a bit distracting and if the book actually has bold text, you'll never notice it. This is fixed easily in the make LRF dialog box.
One other thing that is I feel you don't actually need a header as we should already know what it is we are reading.
But in order to fix the em dahses, I'm afraid that once you have Book Cleaner properly set-up, you'll need to reload from your source and redo any edits you've done because once the em dashes are messed up like they are, the only way to fix them is to hand fix them.
And if the source file you started with is text, convert it to RTF and then load it in as Book Designer has a bug that sometimes text files can have paragraphs split impoperly. So the best formats to load are RTF or HTML.
