Not a strong follow-up to an exceptional series opener. Unlike On a Pale Horse, this book did not have a solid lead character or a witty interchange with the main antagonist. I had much higher expectations for this book, as the character of Chronos (Time) has so many possibilities for adventures through time, but the book only delivered a series of odd adventures through space.
The beginning is dull, with an overlong backstory for the lead that does nothing to get the reader on his side. It takes roughly 20% of the book just to get into character, and even that moment fizzled into a bare sentence of taking hold of the Hourglass. From that point, the book bounces equally between silly and confusing episodes. It appears Piers Anthony got caught up in the Star Wars / Star Trek hype of 1983, as he devotes whole chapters to Chronos taking trips to "other planets". Although this is slightly cleared up near the end of the book, at the time the readers can't help but shake their heads and wonder why this book is relevant.
By the end of the book, the final battle between Chonos and Satan is a yawner. There is no exciting exchange of ideas, no witty dialogue, and no grand release when the hero wins the day. It's more a relief that the story is over.
For a book with such promise, it's saddening that the most interesting character is the ring.
