Hybrid Church in the City [PDF ebook] 
Third-Space Thinking

There has been a growing interest in the rapidly evolving nature of cities in the past 10-15 years, but especially in the last 5 years, and the profound impact this is having upon our understanding of community, belonging and church. This book shows that theology in an urban context has developed way beyond the inner-city nostaligia. It is a challenging, critical and constructive study of the role of the church in cities.
