This book is a mixture of Lord of the Rings + the Grail Quest with a smattering of Harry Potter and the light buddhism the author threw into his Neverness books. While this may sound an unfair way to start a review, there is a strong sense of "I've seen this all before" throughout the whole book, in some cases to the extent that you can predict what's next. Whether this is due to common myth archetypes and situations or due to this being extremely derivative is up to the reader. But there is some very interesting writing here, even with the Deja Vu.
Valashu is a prince and the seventh son of a a king of a small mountain territory constantly warring with his neighbors. Valashu has a vision, and agrees to join a quest for a powerful artifact, the Lightstone, that was lost centuries ago. He assembles a ragtag bunch of friends for this quest, and is hunted by the Dark Lord who wishes the Lightstone for his own purposes. In summary, it is cliched, but Zindell does some interesting things with it. First off, Valashu is an empath. His blessing/curse of empathy is so extreme that each time he kills someone, he shares in the cold despair of their death; enough that he swears to never kill again, and ends up breaking that vow over and over. The novel is written in the first person, so there's an emphasis on internal states, feelings, and growing awareness of things happening.
There are some things familar, for better or worse, for fans of Zindell's work. The hero's best friend is named Maram, but he might as well be Bardo II. Valashu is Danlo, particularly Danlo in the Wild. This may put some people off, but it works in this circumstance.
Beyond all these criticisms, there's an excellent, well-written book here. If you can get beyond the "cliches" in the plot and the ever present sense of deja vu, there's alot of enjoyment to be had.
