Haunted by his tragic past, Jack LeBlanc, a heavily scarred introvert, finds himself volunteering for the clinical trial of a miraculous new tissue-regeneration drug nicknamed Obsidian. Jack and the other test subjects soon discover that the medication is not what was promised. They’re about to find out the hard way that the pills have nightmarish consequences and that Jack’s pained conscience isn’t the only thing with teeth.

With every pill taken, one thing becomes more clear: the path to perfection will be paved with gore. From the author behind Bad God's Tower, Writhe, and Mantis comes a truly unsettling, Cronenberg-style body horror novel that will make your skin crawl and have you questioning every pill you take.
