Book No. 6 "Rivers of London". This series has all the elements I enjoyed from Alan Garner and Susan Cooper, but for adults. I also like London. I lived there for a couple of years from 1972-74 and in recent years we visit at least once a year. Having done all the usual tourist stuff decades ago, we mostly just walk around exploring. By coincidence, I saw an advert yesterday for the latest book in the series which will be out in a few days time.
