I just read and enjoyed a long piece by Rabbi Jack Simcha Cohen. The little biog attached said he was a "prolific author", but doesn't give any indication of whether all of his output has been in a similar vein (e.g. examining Modern Orthodoxy's approach to halacha).
Looking through the catalogues of online retailers, his output seems to consist mostly of collections of answers to specific questions. For example, here is a quote from the blurb to How Does Jewish Law Work?:
....provides both the answers to questions of Jewish law and a look at the process by which the answers are derived. According to Rabbi Cohen, "Halachah, the distinctly unique Jewish legal system, crystallizes the guidelines of Judaism. It makes us into Jews and marks us as Jewish. As such, an understanding of the halachic process provides insight into the inner soul of Jewish life itself."
In this book, Rabbi Cohen explores issues surrounding charity, Jewish communal concerns, repentance and rebuke, marriage and family life, rituals, Sabbath and holiday observances, and prayers.
A companion volume to his previous best-seller, Timely Jewish Questions, Timeless Rabbinic Answers, How Does Jewish Law Work? clearly presents each question and carefully details the process of finding its answer. Through explication of verses from the Torah, talmudic passages, and other sources, the reader receives the answer to the question and is also given the background information to see how a rabbi arrives at the halachic decision.
