When college student Aiden Carraway visits his hometown to confront an unfaithful girlfriend, his drug-addicted twin brother forces him to rethink his priorities.

Despite choosing the right path in life--namely the attainment of a snotty girlfriend and a college education--Aiden harbors a secret crystal meth addiction. Unlike his twin brother Calvin, a junky occultist who openly embraces a slacker lifestyle, Aiden is obsessed with success, terrified of failure, and goes to great pains to hide his vice from everyone, including himself.

As Aiden verges on losing everything to drugs--his girlfriend, his education, his life--Calvin dies. His sudden and unexpected death prompts Aiden to attempt quitting all drugs. In this newfound state of lucidity, Aiden pieces together Calvin's final days, learning more about the private life of his twin brother in one week than he has in the previous twenty years. What he discovers about Calvin is as shocking as it is profound. This newfound knowledge impels Aiden on a quest, an unfinished mission his brother had set into motion, and one which Aiden must see through to the end, no matter the cost.
