Counter book to Eckhart Tolle's Power of Now

I am a Catholic therapist who is a Licensed Clinical Social Worker and a Certified Alcohol and Drug Counselor in Kentucky. I am in a small book club with some ladies at work and our first book (chosen by a collegue) is Eckhart Tolle’s the Power of Now. I have been taking notes furisouly as I read to “enlighten” my group members of the errors in this man’s philosophy. I was wondering is there a Catholic book to counter this stuff? I would be willing to write something, but know I would have my work cut out for me with five children and working full time. Also, I doubt Oprah Winfrey would invite on her show with a differing opinion of the hogwash she is leading the masses of people into.

I need the same help-- some good counter info if anyone has it
please
