Zero Angel

As much as I'm enjoying Song of Ice and Fire, I find the POV shifts frustrating at times, especially because of how seldom most of them overlap. I find myself wanting to skip through and read all of Jon's chapters - or else skip Jon and Daenerys so I can focus on what's happening with the other characters. I don't think it's a good thing I can do that without missing much.
GRRM's success with a multitude of POV characters, I think, is the exception instead of the rule. He's setting up disastrous, independant conflicts all over the map, and it wouldn't work any other way. But even just reading it can be at times a daunting endeavor that wouldn't be worth the investment, I feel, if it wasn't for the quality of his storytelling powers.
This is what I did for the last book I read of his. I was able to do this successfully for (I believe) each character. The storylines started out close together, but by now they are spread to the ends of the kingdoms with little to no overlap. But this has resulted in the entire work not being satisfying. I won't pick it up again until the series is done.
