Query: Amateurish and ludicrous

This was a ridiculous and amateurish novel. This is my first John Saul book and will definitely be my last. Failing to be scary, thought-provoking, interesting, or even plausible, this book is a laughable attempt by Saul to move into science fiction. With only the knowledge of ninth grade biology class, I would be able to disprove nearly every scientific speculation in this sorry excuse for a book. Saul also neglected to include any of the basics of writing in The Presence, ie character, suspense, plot,etc. if you want science fiction/ suspense, try reading Michael Crichton or Robin Cook, not this wannabe.
