Nancy and her friends are on an epic quest to discover the identity of a treacherous Greek scholar in this fifteenth book of the Nancy Drew Diaries, a fresh approach to the classic mystery series. Nancy, Bess, and George are excited to attend Oracle College’s annual Greek mythology themed gala. But the festive sprit turns troubled when a student falls from the balcony mid-speech. Nancy’s investigations quickly reveal this was a case of collegiate sabotage. Can she find the campus menace before someone else gets hurt?

The Professor’s Puzzle is designed as a handbook for new and aspiring professors to help them transition from the independent research of their doctoral program to classroom teaching. Unfortunately, acquiring a Ph.D. often does not involve real preparation for teaching. One cannot assume that mastering content necessarily means one is qualified to teach it. Drawing from years of experience training young faculty members, professor Michael S. Lawson gathers together the best of educational research and practices, leavened with the yeast of Christian theology, so that readers are equipped to put the “teaching puzzle” together. Ideal for aspiring professors in Christian higher education, as well as all who enter the teaching profession, so they may learn artful teaching and careful administration.

This groundbreaking volume investigates the most fundamental question of all: Why is there something rather than nothing? The question is explored from diverse and radical perspectives: religious, naturalistic, platonistic and skeptical. Does science answer the question? Or does theology? Does everything need an explanation? Or can there be brute, inexplicable facts? Could there have been nothing whatsoever? Or is there any being that could not have failed to exist? Is the question meaningful after all? The volume advances cutting-edge debates in metaphysics, philosophy of cosmology and philosophy of religion, and will intrigue and challenge readers interested in any of these subjects.
