Layout essentials: 100 design principles for using grids – is a solid book. I’d like to stress this though: if you’re already working with grids and want to learn some more advanced techniques, this isn’t the right book for you. I think this book can be very useful to those who are just starting with this and want to get a good undestanding of what grids are, and to learn all the basics.
