Ringworld's Children
The Ringworld is like a small slice of a Dyson Sphere, a massive ring with radius slightly larger than 1 AU, spun to simulate gravity on the inside with thousand mile-high side walls to hold atmosphere. In the second Ringworld novel, The Ringworld Engineers, it was revealed that the Ringworld was probably created by Pak protectors, a species cousin to humans with three phases in their life cycle: juvenile, breeders, and protectors. Protectors are extremely territorial, competitive, and intelligent, and will go to any lengths they can to protect and provide competitive advantage for their descendants, as identified by a keen sense of smell. While protectors normally cull out any significant genetic divergence from normal (picked up by changes in smell), a failure in the food supply caused all protectors in the Earth Pak colony to die. Breeders evolved sapience and became homo sapiens.
Something similar has somehow happened on Ringworld and, in the third book, after decades exploring the Ringworld, our hero, Louis Wu, decides to replace the current insane master of the Ringworld, Bram, a protector created from a vampirical species also evolved from the original Pak breeders. Even insane, Bram is still many times smarter, stronger, faster, and tougher than any human, so Louis and his cohorts don't have much of a chance taking him on. Humans and all Pak-descended Ringworld species can still turn into (misshapen/modified) protectors if exposed to tree-of-life root, but Louis is too old to make the transition to protector himself (besides, he likes breeding). He carefully creates another protector, Tunesmith, and, with the help of others, they manage to kill Bram.
Ringworld's Children picks up a few months after the end of the Ringworld Throne. Louis comes out of the autodoc that has been repairing the severe damage he suffered in the fight against Bram. He's also young again, thanks to Carlos Wu's one-of-a-kind nanotech autodoc, after tinkering by the hyper-intelligent Tunesmith. Tunesmith has been busy soaking up all Known Space knowledge, including advanced Puppeteer knowledge from the completely intimidated Hindmost, the former leader of the Puppeteer race and Louis' erstwhile employer. He's also been working on cleaning up some of the mess left by Bram (tens of centuries or more of overdue Ringworld repairs - Bram was a lousy housekeeper, too). More urgent however is the Fringe War, a cold war in the remote asteroid belt at the far edges of the Ringworld system (similar to our Oort Belt). Most of the major species of Known Space have at least a few ships there. The ARM (the UN's police/military forces) and the Kzin have substantial war fleets. All the factions want to learn the Ringworld's secrets. Those fleets have antimatter weapons that could destroy the Ringworld as collateral damage and, for perhaps decades, they've been in a Mexican standoff, but deployments and movement patterns indicate all antimatter hell could break loose in the near future.
Louis' puppet strings are now held by Tunesmith, and since Tunesmith takes some pretty big calculated risks without explaining their rationale, Louis likes it maybe even less than when those strings were held by the Hindmost. Even if they get past the immediate emergency, Tunesmith's likely long-term plans for Louis are far from appealing. He has to figure out how to permanently escape from Tunesmith and the Ringworld without getting blown up by the Fringe War or triggering an apocalyptic attack on the Ringworld. His only chance at escape from Tunesmith's vastly superior intelligence is that Tunesmith is heavily distracted planning on how to deal with the Fringe War.
In earlier ringworld novels, when Louis and his co-explorers made first contact with native Ringworld population groups, they would play the "God Game," first getting their story straight and consistent before conning the natives to obtain knowledge or food. That dialogue technique is used here again, including when Louis uses it by himself to figure out scenarios he can use against Tunesmith. Part of my mind was a little distracted, thinking "Is this how Niven works out the plot outline of novels, before fleshing out individual scenes or chapters?" But the rest of my (virus-addled) brain was racing along trying to figure all the possibilities where Niven or his characters might be going. Even so, Niven still managed to completely surprise me once near the end, because I'd let myself get distracted and miss a couple of the better hidden clues.
Along the way, Niven ties up a lot of loose ends and answers a lot of questions, about the Ringworld and about some other phenomena in the Known Space universe. The plot has few slow points, and almost none in the second half of the book, hiding fairly well Niven's slightly-less-than-usual weakness at character development. This novel should earn Niven another Hugo nomination
If you're a recent SF reader and can't handle the lack of ubiquitous computers or the ESP/Psionics that dates some of Niven's more famous and popular 60's and 70's era stories (when the Amazing Randi hadn't yet debunked Uri Geller and most others of his ilk), you may find his Ringworld stories more palatable. Pak don't need or want computers on the ringworld, and there's passing mention of psionics only because of the conventions established in other Known Space series. If you like older 60's or 70's-vintage Niven stories because of the imaginative aliens, environments, or inventions, you'll almost certainly enjoy reading this book. Finally, if you've liked any of the other stories in the Ringworld or Known Space series and were left wanting more, you need to read this book.

About 15 years ago I told an anonymous person in a chatroom on GEnie that I thought he was a poo-head for not considering the hazzards of debris in orbit, turned out the anonymous was his wife.
:)
I agree with you about JP.
I sat next to his wife at the '92 WorldCon, in Orlando, during his talk about reusable space vehicles.
She is very nice and I think she realizes he is a bit of a prat...

Hmm did something for me, the quote:
But being home with a virus this weekend, and having run out of new Anime DVDs to watch,
I have mostly found on a Friday it's not the weekend, I dearly wish for the late afternoon meeting or system problem to to bother me on a Friday, particually before watching DVDs all day and then reading a book and writing the review ready for slashdot.
I stopped watching the Tolkien Trilogy after the second movie.
Can't say as I blame you. It was hard to stay enthusiastic about the films after seeing Aragorn fall off a cliff, Faramir hauling Sam and Frodo to Osgiliath, then Frodo trying to hand the Ring to a Nazgul. ROTK had it's share of plot changes too. (cutting the final showdown between Gandalf and Saruman was criminal -- but at least it will (allegedly) be in the extended edition) I find it helps to think of it as, "Peter Jackson's Lord of the Rings", not the canonical version.
