The Other Boleyn Girl by Philippa Gregory?

I really don't know, i couldn't finish the second part of the book. it all seemed way too obvious what was going to happen. the blurb tells you exactly that anne will take over from her sister in seducing the king and well i know that the king marries her from general history so i just couldnt force myself to read it. does it get any more mysterious or go any further than that?
