'If you believe that the unexamined life is not worth living, then this is a must-read. These are the deep questions of life that not enough of us are asking, and we're all paying a price for it. In a world where too many of us--even Christians--settle for the shallows, this is a beautiful, profound, and, at times, challenging look at the depths. Mark tackles some of the hardest questions of existence and traces out the meaning, purpose, and further questions that will make your soul question, dream, and, ultimately, hope again.'
