Iron Fist by Aaron Allston is volume six of the X-Wing series. After their ingenious coup in book five, the Wraiths have earned a reputation. So the shady squad is padded to full strength and sent on a similar, yet potentially more dangerous but also more worthwhile mission: Wraith Squadron is to pose as pirate gang in order to be employed by warlord Zsinj and then expose him to attacks by New Republic military.
Iron Fist is a fun, action packed read despite some sad episodes. Similar to the prequel, the mission itself gives plenty opportunity for curious twists and the less-than-correct attitude of Wraith Squadron makes for lots of inter-character humor. Introduction and development of the new guys is too hasty for my taste, but still acceptable for the format: there are many leaps in time that keep proceedings plausible but also skip exactly those vital integration episodes.
All in all, Iron Fist is a worthy X-Wing book and maybe even one of the better ones, given that there are losses and consequently sad moments.
