Burdened with the loss of his parents, he finally has an opportunity for closure. For revenge. How far will he go to get it?


Isaac Sage has struggled with depression and anxiety over the loss of his parents for 15 years. When he finds a clue to the culprit behind his parent's death, Isaac chooses to take action under the guise of a vigilante in the cities of New Manhattan.

As Isaac encounters far worse odds than he anticipated, veteran detective John Saint tracks down the whereabouts of Diablo, a drug lord that smuggles a corrupted all-cure medicine. Near the end of his tenure, Saint wishes to deliver a justice he has not seen since he began working as a detective decades ago. Little do they know, however, of the drug lord's mutated powers to create explosive fires thanks to the strange properties of this medicine.

It's a race for justice. It's a pursuit for revenge. The question is, how far would Isaac be willing to go to exact his vengeance?

Mad City is the first book of a thriller sci-fi series that features fast-paced action, a multitude of compelling character perspectives, unique plot twists and intricate layers of drama.

If you liked American Gods, Jack Reacher, and Netflix's Daredevil, then you'll love the beginning of Victor Vahl's page-turning spectacular.
