I’m currently reading an excellent novel set in the Boer War by Joyce Koetze which I’m trying to help her get published. It’s an epic story but her structural planning is so good it even includes phases of the moon. Such things give a work a lustrous twinkle of authority. In Joyce’s story, her spies travel in the new moon (will they evade capture?) and her heroine uses the moon to avoid pregnancy (will it work…?).
To find out the phases of the moon for the period you are working on, get ‘QuickPhase’ – a downloadable programme from moonconnector.com. It claims to cover all history. (I’ve yet to get a copy as we’re changing computers soon).
