The last book in the Space Tyrant series is a fair different from the rest of the series books. Its not written by Hope Hubris him self but written by his daughter Hopie and is really the biography of Hope's sister Spirit.
When Hope dies at the end of last book, there where a lot of loose ends. Hopie did get to know who her father and mother was, and no I'm not going to reveal that, you have to read the book.
