Book on evolution of stars?

I've check the recommended Physics reading list but couldnt find what I was looking for, which is a book on the evolution of stars. I've a GCSE Astronomy textbook which covers it in little detail, and I've check amazon, but everything wwas £30 plus, except for this: http://www.amazon.co.uk/Birth-Death-Sun-Evolution-Subatomic/dp/0486442314/ref=sr_1_13?s=books&ie=UTF8&qid=1300300893&sr=1-13

(Incidentally, anyone read it? Any good?)

So does anyone know of a good book on this that;s not too expensive? Thanks!

What course exactly are you studying? I did IB physics, if you live in England I've no qualms mailing you my old textbooks if you want them.

One of the oldest but still good is the one by my old lecturer at Sussex - Roger Tayler - the structure and evolution of the stars
