This is an extremely informative book with loads of information about star sign combinations.
When you first see it, you'll notice how THICK it is. This is because Linda Goodman has taken the time to write an in depth analysis of each star sign relationship. She first starts off with an intro of what each sign means and goes on to how they "are" together.
For those of you that want a "light read" you WON'T get it here. This is a very PRECISE book and if you're not interested in the nitty gritty, you may find that there's a lot of irrelevant information. So if you just want to know the bare bones, "Are Libras compatible with Tauruses???" you'll find yourself flicking through pages and pages to find the paragraph you're after.
I recommend this book to people who are interested in exploring the astrological LOGIC behind why some star signs are attracted to each other and want to learn more about their own or their partner's characteristics in depth.
If you're after something fun and easy then I recommend "Sexual Astrology", but definately go for "Love Signs" if you have a burning interest into the laws of attraction.
