If you loved Bitter Seeds you'll love this. The novel takes it on 20 years into the early 60s with Cold War paranoia. The author wisely steered clear of the obvious cultural references and instead sets up an atmosphere of English mundanity.....though how mundane is it when warlocks are battling ex-nazi supermen?! Descriptions are vivid. Characters are realistic and not infallible - guilt is a major theme - though you end up feeling for each one as a possible occult apocalypse looms.
Though not much happens in the first 2/3 of the book, this is more than paid back with an intense final third which really sets the situation up for the finale of the tryptich. Classy!
