At least one reader (BungalowBarbara) recommends reading the series in approximate publication order:
2009-02 "Angels' Pawn"
2009-03 Angels' Blood
2009-09 "Angels' Judgment" (it would also work to read the two novellas before Angel's Blood, or both just after)
2010-02 Archangel's Kiss
2011-10 "Angel's Wolf"
2012-02 "Angels' Dance" (could be read this early, or in strict publication order, as you prefer)
2011-02 Archangel's Consort
