A review by ultimatumman
The Ringworld Throne by Larry Niven

1.0

Terrible. The first two books in this series were great. This book took an unexpected twist early on when the focus became the vampires that apparently live on the ringworld. It was a little weird, but it could have played out well had it been relevant. On the ringworld there are various humanoid species that have evolved individually. Between these species there is a custom called rishathra, which is sex with another intelligent species. Though introduced in the previous novel, the author became OBSESSED with rishathra in this book. It seemed like you couldn't go five pages without talking about or performing it. It started with the vampires which used pheremones to attrach their victims to mate with them. This could have made sense since this would provide the vampires with additional future food, but it turned out not to be a different spin on vampires, but just another part of the author's obsession with sex. There wasn't any point to this book besides aliens hooking up.
