I would recommend:
The AB Guide to music theory parts 1 + 2

I use these books all the time to help with my college course, and the classes are based around whats in the bokos too.
Book 1 covers everything up to grade 5 theory, book 2 covers 5 - 8 I think.
So beginners will definately only need to buy book 1.
Just a suggestion :)
