Loanshark Frank Powers lives by two simple philosophies:

Stay loyal to your friends.
You sign, you’re mine.

Go back on your word, and Frank pays you a visit. If he likes you, and if he believes you, the brass syringe stays in his pocket.

Now Frank must become a savior instead of a shylock. Many lives now depend on his strength and old skills shaken free of mothballs.

Gangsters, guns, girls, and greed. Agonist rides a rollercoaster through the dips and dives of romance, rage, and redemption.

An excerpt from Agonist:

Frank felt it happen.

The old coldness crept in, like it used to back when he hurt people for a living. Numbed detachment flowed from his head down to his feet. He felt his face go flat, his eyelids dropping halfway. He straightened, back stiff and hands relaxed at his sides.

Showtime.
