Read: The Tenth Chamber
Cooper's The Tenth Chamber is mixture of historical and crime fiction, its three timelines are set some 30000 year ago, during the medieval ages, and in our current time. The quite compelling story joins a longevity theme with some conspiracy theory.
All in all, the elements of the story are not overly original. There are monks, an old encrypted text, life-span enhancing organic potions with an unavoidable side effect, and a government cover-up. Indeed, I had a feeling of deja-vu when I read the novel. Yet, Cooper's style is enjoyably suspenseful. There is no padding. The length and the pace of the story are just about right. In short a rather good book, not exceptional but not bad either.
