This is a novel based on the comic series created by Matt Wagner. It is written by Greg Rucka and accompanied by illustrations from Matt Wagner. The story follows Susan, a grendel who has a past highly involved with the empire, including having been lovers with the sister of the empire and part of the rebellion to bring Jupiter to power. This book follows her after the empire has once again collapsed at Jupiter's murder. She is looking for the Paladin, the Grendel-Prime, that once protected Jupiter as a boy. The story was good, but at times rather predictable. There were a few instances of cliched plot points, so that was a little disappointing, but overall it was good. 
 The illustrations by Wagner were a nice addition, mostly done in a fairly loose style. One thing I found odd was he seemed to have a desire to Always illustrate any nude scenes, even if there was something much more interesting on the page. 
 Overall, a decent book but not spectacular.
