Promise of Blood

I originally gave this 3 stars a couple years ago and thought it was mediocre.... What an idiotic review and I can't believe nobody roasted me in the comments.

This book has everything just about. There is a mystery, character development is great, and the plot is great!
You have powder mages than can control the path of a bullet with mile long accuracy. They can also snort powder and get superhuman strength.

Tamas and his son Taniel are one of these and they have staged a coup, slaughtering every person in the nobility except for one child.

Nila is a washerwoman who saves said child and then wants to kill Tamas before he can finish the boy off.

Adamat has a “third eye” where he can see things others can't and has an unshakable memory. His talents led him to a successful P.I. career which Tamas is utilizing. He wants to know why every nobility says a mysterious phrase before being killed.

There are multiple side characters that are a lot of fun as well!
