Ani Maamin

If the Documentary Hypothesis keeps you up at night, this is the book for you. As the title indicates, there are two parts to the book: a refutation of the DH and a reconciliation with Maimonides's 13 Principles. The latter is not as interesting as the former. The prose is clear albeit a touch academic and overlong in the second half, but overall a book that will reset your worldview. Highly recommended.
