The Excalibur Alternative
This is an interesting mix of a novel. It's science fiction, yet the characters are from the medieval times. I've read the book before, more than once and I greatly enjoy reading it.
I'm sure I've seen the plot before, where humans end up acting as soldiers for extraterrestrial races, but I can't think of which other authors or books have done it, aside from David Drake's anthology Foreign Legions which I'll admit I haven't read. I know of it from the author's note inside this book.
The one thing about The Excalibur Alternative that I don't especially care for is the way the ending feels rushed to me. For almost the entire book, we are following one character's point of view. Within the final pages of the book, we are abruptly thrown into another character's point of view and the book is finished from that point of view.
Still, as with Weber's other science fiction novels, this is a good book, and one I'll probably be re-reading sometime again. It's certainly a book that stays in my permanent collection.
It's certainly a book that rather leaves me wondering about what will happen after the book ends.
