Vengeful Spirit by Graham McNeill
My rating: 5 of 5 stars
In a very refreshing change from other Black Library books, Vengeful Spirit actually has some traces of science fiction in it. Battles both in space and on the ground are well described, and for the first time, I did not have the feeling that the only use of space ships is to get Marines as fast as possible into hand-to-hand distance.
Also, even Space Marines can die in their dozens when fighting in the general vicinity of Titans, the description of which cuts those transhumans down to a bit more manageable scale.
Overall, well worth the admittedly steep price Black Library is asking for this volume.
