Book Reviews - Should You or Shouldn't You?

There's been an interesting discussion going on among members of a writing group I recently joined about whether or not we should review books. It was an interesting discussion.

Then today author Roni Loren talked about it on her blog. You can find today's post here. I think she raised some very good points and reached some of the same conclusions I have.

What about you? Do you review books and tell it all, even if you hated it?
