esoteric Astrology books

Be good to know what esoteric astrology ('EA' from now on because, you know, typing) books, apart from Alice Bailey, you've found useful? I kind of collect them and have a list, which I'll pop up here once ready .

The first I read was Alan Oken's EA, although (big point for me which I've tried to rectify) it didn't cover aspects. Many others since then, with varied results.
