My father still hasn't actually cracked any of the books—so, no, he still hasn't noticed. I think I'm just going to have to tell him. Maybe I should break it to him gently.

"Everyone here who hasn't had a book dedicated to them, take three steps forward. Whoops, Dad, hang on a second.

These people saved my life. Without their help, I would never have finished these books. You may apply the appropriate punishments.

As always, shout-outs to all my homies on the Tad Williams List-serve and the message boards of the TW Fan Page and Guthwuff.com's MS&T Interactive Thesis.

And of course, no acknowledgments would be truly acknowledgmentacious without mentioning my wonderful wife Deborah Beale, my lovely and talented agent Matt Bialer, and my brilliant and patient editors Betsy Wollheim and Sheila Gilbert. My kids Connor and Devon didn't really help much, but they sure make life more interesting (and the need to finish and sell books more acute), and Connor did type a bunch of consonants into my manuscript at random for me to use later, so I guess they belong in here as well.

Wet, terrified, with only the companionship of trench-mates Finch and Mullet to keep him sane, Paul Jonas seems no different than any of thousands of other foot soldiers in World War I. But when he abruptly finds himself alone on an empty battlefield except for a tree that grows up into the clouds, he begins to doubt that sanity. When he climbs the tree and discovers a castle in the clouds, a woman with wings like a bird, and her terrifying giant guardian, his insanity seems confirmed. But when he awakens back in the trenches, he finds he is clutching one of the bird-woman's feathers.

In South Africa, in the middle of the twenty-first century, Irene "Renie" Sulaweyo has problems of her own. Renie is an instructor of virtual engineering whose newest student, !Xabbu, is one of the desert Bushmen, a people to whom modern technology is very alien. At home, she is a surrogate mother to her young brother, Stephen, who is obsessed with exploring the virtual parts of the world communication network—the "net"—and Renie spends what little spare time she has holding her family together. Her widowed father Long Joseph only seems interested in finding his next drink.

Like most children, Stephen is entranced by the forbidden, and although Renie has already saved him once from a disturbing virtual nightclub named Mister J's, Stephen sneaks back in. By the time Renie discovers what he has done, Stephen has fallen into a coma. The doctors cannot explain it, but Renie is certain something has happened to him online.

American Orlando Gardiner is only a little older than Renie's brother, but he is a master of several online domains, and because of a serious medical condition, spends most of his time in the online identity of Thargor, a barbarian warrior. But when in the midst of one of his adventures Orlando is given a glimpse of a golden city unlike anything else he has ever seen on the net, he is so distracted that his Thargor character is killed. Despite this terrible loss, Orlando cannot shake his fascination with the golden city, and with the support of his software agent Beezle Bug and the reluctant help of his online friend Fredericks, he is determined to locate the golden city.

Meanwhile, on a military base in the United States, a little girl named Christabel Sorensen pays secret visits to her friend, Mr. Sellars, a strange, scarred old man. Her parents have forbidden her to see him, but she likes the old man and the stories he tells, and he seems much more pathetic than frightening. She does not know that he has very unusual plans for her.

As Renie gets to know !Xabbu the Bushman better, and to appreciate his calm good nature and his outsider's viewpoint on modern life, she comes to rely on him more and more in her quest to discover what has happened to her brother. She and !Xabbu sneak into the online nightclub, Mr. J's. The place is as bad as she feared, with guests indulging themselves in all manner of virtual unpleasantness, but nothing seems like it could have actually physically harmed her brother until they are drawn into a terrifying encounter with a virtual version of the Hindu death-goddess Kali. !Xabbu is overcome, and Renie, too, is almost overwhelmed by Kali's subliminal hypnotics, but with the help of a mysterious figure whose simulated body (his "sim") is a blank, with no features at all, she manages to get herself and !Xabbu out of Mister J's. Before she goes offline, the figure gives her some data in the form of a golden gem.

Back (apparently) in World War I, Paul Jonas escapes from his squadron and makes a run for freedom through the dangerous no-man's-land between the lines. As rain falls and shells explode, Paul struggles through mud and corpses, only to find he has crossed over into some nether-region, stranger even than his castle dream—a flat, misty emptiness. A shimmering golden light appears, and Paul is drawn to it, but before he can step into its glow, his two friends from the trenches appear and demand that he return with them. Weary and confused, he is about to surrender, but as they come closer he sees that Finch and Mullet no longer appear even remotely human, and he flees into the golden light.

In the 21st Century, the oldest and perhaps richest man in the world is named Felix Jongleur. His physical body is all but dead, and he spends his days in a virtual Egypt he has built for himself, where he reigns over all as Osiris, the god of Life and Death. His chief servant, both in the virtual and real world, is a half-Aboriginal serial murderer who has named himself Dread, who combines a taste for hunting humans with a strange extrasensory ability to manipulate electronic circuitry that allows him to blank security cameras and otherwise avoid detection. Jongleur discovered Dread years before, and helped to nurture the young man's power, and has made him his chief assassin.

Jongleur/Osiris is also the leader of a group of some of the world's most powerful and wealthy people, the Grail Brotherhood, who have built for themselves a virtual universe unlike any other, the Grail Project, also called Otherland. (This latter name comes from an entity known as the "Other" which has some important involvement with the Grail Project network—an artificial intelligence or something even stranger. This powerful force is largely in the control of Jongleur, but it is the only thing in the world that the old man fears.)

The Grail Brotherhood are arguing among themselves, upset that the mysterious Grail Project is so slow to come to fruition. They have all invested billions in it, and waited a decade or more of their lives. Led by the American technology baron Robert Wells, they grow restive about Jongleur's leadership and his secrets, like the nature of the Other.
