"To Sail Beyond the Sunset" is the fifth and last book in the world as myth series. It is written in the style of a memoir of Maureen Johnson who is one of the members of the Howard Families, and Lazarus Long's mother.
If you haven't read the other four books in the series then seriously consider picking them up and reading them in order otherwise this book will not make a whole lot of sense, as it builds directly on the last book "The Cat Who Walks Through Walls", and before that “The Number of the Beast", "Time Enough for Love", and “Methuselah's Children". Pixel (the Cat) however is better featured in this book even though he is the title character of "The Cat Who Walks Through Walls".
As mentioned this book is written in the format of a memoir dictated by Maureen Johnson/Smith while she is in jail awaiting trial and possible execution by a rather mysterious group of people, after waking up in a strange hotel room with a corpse beside her.
Outside of this, this novel is primarily about sex. There is no other real theme to the book as it details Maureen's life, her loves, her children, their lives, and fills in a whole lot of the backstory of the Howard families. Which is a good thing because the previous books do leave a number of questions unanswered.
This was also to the best of my knowledge Robert Heinlein's last novel, as he died in 1988. Mr. Heinlein's views on gender relations, sex, religion, marriage, and many other social topics come through very clearly. But this is not necessarily a bad thing (even though it will likely offend some of the more puritanical readers-Mind you they probably wouldn't be reading this book anyways), as the rather odd relationship that various cultures today have towards these topics can easily be accounted for as the characters live some 2000 years in our future, and the chances of our customs not changing in that time is zero.
All in all it was a very good series, but you do have to read it in order for it to make sense.
Happy reading.
