Opoponax is otherwise known as myrrh--yup, an ingredient of perfume. But this little fact has nothing to do with this story, which is pretty standard science-fiction fare--scheming artificial intelligences and corporations, alien artifacts, plans gone awry, world in jeopardy kind of stuff. But Brosnan has an undeniable gift for science-fiction. Like the master chef that can make an unforgettable meal with any available ingredients, Brosnan has managed to craft a story involving gender issues, nanotech, AI and the internet that does not seem dated even though this book is over ten years old. And what makes Brosnan's science-fiction so enjoyable is that his characters are as believable as his science.
My first Brosnan book, "Mothership," was so good that I went looking for anything else he wrote. This was fortunate, because the cover art on my edition of Opoponax is so abominable that I would probably not have picked it up in a store. Reading Brosnan is a treat--highly recommended.
