Query: Very Disappointing...

DisappointingI have read all of Jack McDevitts books and have enjoyed everyone... he is a master of the space opera genre, well he was! Odyssey just does not work... it lacks depth, story line and consistency with his previous works in the `Hutch' series. I kept reading in the hope that the story line would come alive but unfortunately it limped to an unsatisfying conclusion... so many loose ends and you are left with wondering who is a good guy and who is a bad guy...Odyssey is extremely disappointing and not a fair reflection of McDevitts other works... If this is your first book by this author do not despair... many of his other titles are excellent science fiction.
