I believe it converges by the ratio test but my book says it's "inconclusive" because of a comparison to the harmonic series. I don't get it....... any help please?

That's very strange. You can say that a particular test for convergence is "inconclusive" but that doesn't apply to a series itself! Obviously, any given series either converges or it doesn't. That's true whether we know which is true or not!
