progressed charts

While Rushman's Art of Prediction is a good primer, I'd like to know if there are any good books y'all would recommend regarding progressed charts (esp in terms of timing), and those that will covered progressed house cusps. I'm looking for something very in depth.

The Technique of Prediction by Ronald C. Davison.

It covers cuspal progressions too.

Gloria.

Berrnadette Brady's Predictive Astrology (The Eagle and the Lark)

This covers transits, progressions and other methods - it's expensive but Brady is right up there on Predictive Work.

Also Christine Shaw - Predictive Astrology which is heavily into progressions

Nancy Anne Hastings - Secondary Progressions good alround book on Secondary Progressions

Robert Blaschke - Progressions - slim volume and a bit demanding

and if you're really into it - Alan Leo's Progressed Horoscope. The first 'real' book on the subject.

Thanks for the suggestions
