Despite being a long-term Ludlum fan, I had previously been hesitant to jump into the Covert One series. This changed when I picked up Cassandra Compact in an airport bookstore. Having enjoyed Cassandra Compact, I decided to go back to the beginning of the series. With The Hades Factor, I was not disappointed. The tale, although lighter and clearly not nearly as complex as the typical Ludlum, kept me turning the pages. This book, which grabs the reader early and does not let go, contains much of the suspense and plot twists that Ludlum aficionados have come to love in the conspiracy-thriller genre. If you are considering picking up the Covert One books, I would recommend starting with The Hades Factor. It is a very quick read and provides a nice foundation in terms of character building for future works in the series.
