Daniel Abraham's The Long Price Quartet(
A Shadow in Summer, A Betrayal in Winter, An Autumn War and
The Price of Spring) is excellent. The books stand alone plotwise but since they contain spoilers for the earlier volumes.
And he is two books into a new series which has been compared to ASOFAI, The Dagger and the Coin.
