Full disclosure: I had some small part in helping to prepare this book for publication.
Warrior of the Ages
Why should you read Warrior of the Ages? Great story; well defined characters who are easy to like (love); an unusual idea of immortality (dying some thirty times a millennium); an easy, flowing narrative style.
Why not read it? I've given it thought, and for the reader of fiction, especially speculative fiction (a rather wide genre), i can only think of one reason: There is a religious element, in that some form of non-corporeal beings form a part of the structure of the book. On the one hand, this might be enough to turn some off; on the other, it's only religious in the sense that A Bear Called Paddington is ursine. In other words, that's no reason not to read the thing.
To be perfectly honest, i love this book; and i am not shy about spelling out the flaws of books i read and review (see others of my reviews ~ this one ~ or ~ that one ~ for proof).
