Why is the paper copy 1000 pages and this ebook 250 pages? Same price? For a condensed novel?

Tie first book in this series was really good SF. Since then, it's been a medieval slog. Since this is the last in the series, I thought the author might finally wrap up what is to me a little side plot, and get back to the main plot of humanity fighting genocidal aliens. But no... Just more court politics and sea battles. Yawn.

This is a great series and with this book it just gets better. The only negative is that it badly needs some human editing. Obviously this passed through some OCR or bad editing software and many words are mangled into fragments 'inc re ment' instead of 'increment'.
