I've been reading Nietzsche for almost 10 years, and this is one of two secondary sources that I keep close to me when thinking about Nietzsche. Tyler Roberts is dead on in examining Nietzsche's critique of Christianity, religion, and asceticism. It shows just how "religious" Nietzsche was, not to undermine his critique of Christianity, but to show in what ways it is accurate, and in what ways Nietzsche was wrong.

This book really opens up a space for a Christian to read Nietzsche and pull out some of his deeply emotional/spiritual gems while understanding that Nietzsche doesn't have a full picture of Christianity.
