Query: Fake Reviews?

I have a suspicion that the majority of the reviews below are contrived(possibily by Ivey's marketing people) to bolster the status of this book. It's as though someone was told to write a positive review every 2 weeks. All of the reviews sound the same, and nearly all of the reviewers have only reviewed this book. Conicidence?
