I'm homeschooling teenage boys, and am looking for a short book that explains what theology is, and either another short book or the same one, that explains the Anglican liturgy and service etc. My aim is to help the boys understand the Anglican service more so they feel more a part of it ... rather than something weird that adults do. There is 'Theology for Dummies' - can anyone better that? Better still, are there any freebies out there? Upbeat or witty writing would be a further bonus.
