Temptation comes in many forms and for Dagen, that form is Onyx.  They're frequently rivals, going after the same information or artefact.  And just when he thinks he's pipped her to the biggest prize yet, some magical slight of hand leaves her holding the prize!

Onyx is a reluctant mage.  With the childhood (see t0rtur£) she endured you can understand why she tries to stay under the radar.  But with their joint enemies closing in, it's time for Dagen and Onyx to join forces and rout out the enemy.

There are still some big twists and reveals to come - totally called one of them!  However, there are plenty of layers to the story to get stuck into - blood debts, finding out who the true Lone Wolf is, Onyx background, etc.  

Solange and Charles are back to their murky best and you really can feel no redemption from them at all!  There is some serious mistrust for Dagen and Onyx to wade through, perfectly warranted on both sides.  But the chemistry between these two is palpable.  The ribbing between the three lone wolfs was really enjoyable but it's their other halves who really bond them together.

I'm hoping that the Lone Wolves will pop up somewhere in the future.  But I'm really intrigued to see if a certain vault owner gets a book in some future series?!?!?!
