This is a really practical guide to the breadth of possibility to be found in Common Worship.
It assumes some knowledge (not much), and is packed with helpful guidance, signposts and practical tips. I found the chapter on Initiation Services particularly helpful.
It is not really a book to be "read in one go", it is more a point of reference and companion when planning worship. Use it as a handbook, or a refresher.
Even if you "know it all" there will still be stuff in here that may well remind worship leaders of something useful and effective that they tried once or twice some time ago and then didn't use again.
Clearly this book has been produced with much care, as well as a deep affection for and knowledge of Anglican Liturgy.
