I read When Skeptics Ask as a part of an apologetics course that I am taking through Biola University. It is a good overall introduction to apologetics and reasons for the faith. It covers several different areas such as morality, questions about Jesus, questions about evolution and so forth. Geisler is a good communicator. Other books are better suited for specific questions, but as a general overview, this is a good start. 3.5 stars.
