Barb and I have now read this stand-alone fantasy novel twice, the previous time being back in the early 90s (I remembered more of it than she did, but given the lapse of some 30 years, much of it was like a new read). When we originally acquired the book as a flea market purchase, Piers Anthony was familiar to us (mostly as the author of the humorous fantasy Xanth series); but we'd never heard before of his co-author, Robert Kornwise. As we learned from the 17+ page Author's Note by Anthony which concludes the book, there was a good reason for that. Robert (known to his friends as Rob) was an intelligent and popular teen growing up in small-town Michigan in the 80s. Anthony was his favorite author, and his primary inspiration for embarking on a fantasy novel of his own. But while it was in progress, he was tragically killed in a car accident in Dec. 1987, at the age of 16. Some of his friends, who were aware of his project, sent his partial manuscript to Anthony, and invited him to consider a posthumous collaboration. With the permission of Rob's family, he agreed. The present book, copyrighted in 1989 in the name of both authors, is the result.
Of the book's 12 chapters, Rob wrote chapters 1-4, and 7-9. (The original chapter 5 was lost to a computer glitch, and he died before he could replace it.) Anthony wrote the rest, inserting two chapters rather than one into the gap, and also polished and expanded on the text of Rob's chapters; but as he explains in the Author's Note, he kept virtually all of the original text, and in developing the completed plot did his best to follow Rob's literary vision and intent, as far as it could be known from the available clues and interactions with his family and friends. This Note itself is also a moving tribute to the co-author Anthony never actually met, as he came to know him through these people's memories, and a poignant bearing of Anthony's own soul as well. A collaboration of this type is unusual in the modern book trade; but it became a deeply emotional project for the older author, whose dearly loved cousin (also smart and multitalented) died when both boys were in their teens. For Anthony, it became a way to, in some sense, find healing for the tragedy represented by these premature deaths.
Our story begins in Rob's native Michigan, with 17-year-old protagonist Seth Warner, against his better judgment, at a teenage New Year's Eve party with a friend (who was trying to get the attention of a particular girl). Seth's in many ways probably an alter ego of the younger author: both are smart, athletic, level-headed and mature young men; ethnically and religiously Jewish and serious about their belief in God and their desire to do the right thing; caring about both people and animals; into hiking/camping and winter sports. Their family structure is very similar; and they're even both trained in a real-life Oriental martial arts form, Ryu Kyu No Te. But in the first chapter, an altercation with a gaggle of quarrelsome and drunken or stoned "punkers" out for mayhem leads to a hasty retreat, a pursuit, a car wreck, and an accidental plunge through the thinly-frozen ice on the local lake, to what Seth's convinced is death by drowning. However, he wakes up on a warm beach --and soon finds himself in a conversation with a talking tree.
As we presently learn, he's on an alternate Earth in a different "plane" of reality (and in this one, Plane 4, magic works). Long story short, he's one of the four diverse Chosen, one from each of the known planes, brought here by a magical call, in response to a prophecy, through a near-death experience which left a split-off doppelganger in his place. These four Chosen must combat the machinations of an ultra-powerful and nefarious sorcerer (named --what else?-- Nefarious :-) ), whose drive for absolute power is, in some murky fashion, distorting and threatening the moral order of all four planes. So, this disparate band is soon off on a quest to confront the wizard; but they don't have a yellow brick road to follow, and the journey will be fraught with challenging and potentially lethal dangers. (Not to mention a very uncertain outcome awaiting at the end of what may be a suicide mission.)
Anthony was the dominant stylist here, in the final shaping of the prose; and both authors had very compatible visions. So for readers who've read much in the Xanth corpus, there's a somewhat similar feel, except that the tone is more serious and Anthony greatly curbs his penchant for bringing far-out puns to life. (Though he doesn't totally check it at the door; watch on Earth Plane 4 is often kept by Sen-trees....) His characteristic very strong ethical orientation is noticeable here too (and both collaborators clearly shared it); ethical questions and considerations are a major theme, and will bulk large in the denouement. And though Anthony is by his own statement an agnostic, his ethics are of the traditional, altruistic sort taught in the Jewish-Christian tradition (which Anthony believes, in keeping with the natural-law tradition, are discoverable by reason); at one point here, Seth even approvingly quotes Jesus' words, "What does it profit a man to gain the world, if he lose his own soul?" though without explicitly citing the source. The plot is well constructed, and the narrative is fast-paced. Although the target audience is YA, the tale can appeal just as much to adults (Barb liked it at least as much as I did).
Seth is the best developed character, followed by fellow Chosen Tirsa, and Rame, the faun from Plane 4; but on the whole I'd say the storyline is more plot-driven than character-driven. The episodes of the journey tend to feature a "problem + solution" structure; that is to say, a challenge presents itself, and is overcome by some artifact or talent a member of the group can bring to bear. (A strong theme is the value of cooperation and teamwork.) I was inclined to associate this type of structure with computerized video games (although I don't play them and am no expert!), until I remembered that in 1989, those probably couldn't have been of much influence. Where culture and politics are concerned, the world-building is not very strong, and the problem of different languages is handled a bit improbably. But none of these points were deal-breakers. There is a romance, but it's relatively low-key, and clean. Technically, Tirsa could be counted as an action heroine, but combat action scenes are actually very sparse. In Anthony's words, the book "does not dwell unduly on sex or bloodshed." There's also no bad language. (There is some non-gratuitous nudity, but it's not described salaciously, and is treated as something that should be taken in stride, without disrespectful or unwholesome thoughts about it.)
From my memories of the prior read, I was expecting to rate the experience at three stars; but after this one, I felt it deserved four. I'd recommend it to most fans of traditional fantasy, especially those who like a self-contained tale that doesn't force you into a long-drawn-out series.
