this is a really, really good book on houses.
it starts off with a shortish section on the maths and astronomy of the houses etc (which fortunately isn't really necessary to understand the rest of the book), and then a chapter on each house follows. next, a look at each sign and planet through the houses, for example 'mars and aries through the houses'. in each of these sections one to three pages are devoted to each placement, e.g. 'neptune in the first', '..second', '...third.'etc.
everything you may want to know about houses is included, and the book would be great for someone who wanted to dip in, maybe for a look at their own chart or a friend's (if they already had it done), or for a professional. however it isn't for you if you want newspaper-style 'astrology' (and a pity if you do!).
because of its division into sections, it's perfect for a quick read when time is short, or a more lengthy one.
