A Feast for Crows is book 4 in George R.R. Martin's Epic fantasy series, A Song of Ice and Fire. It's unlike its predecessors in that it focuses on a subset of characters and has no chapters at all related to several others. I forgive it, it's still awesome.
The rest of this review will contain minor spoilers in that I will mention characters who are still alive to have a point-of-view (POV) (at least in the beginning) in book 4.
