I found this "survey" to be rather superficial and it focused too specifically on Christianity. The chapters on the nature of experience, knowledge, and wisdom in theology were interesting.
Book Description (from Amazon.com)
This Very Short Introduction provides both believers and non-believers with a balanced survey of the central questions of contemporary theology. David Ford's interrogative approach draws the reader into considering the principles underlying religious belief, including the centrality of salvation to most major religions, the concept of God in ancient, modern, and postmodern contexts, the challenge posed to theology by prayer and worship, and the issue of sin and evil. He also proves the nature of experience, knowledge, and wisdom in theology, and discusses what is involved in interpreting theological texts today.
