"Seventeen-year-old Finn and his twin sister, Faith, have grown up in a trailer full of neglect, mental illness, and abuse. Both bright and driven, the siblings are entrepreneurs: Faith with niche handicrafts, and Finn with dealing any drug he can get his hands on. When he stumbles upon indigo, a powerful hallucinogen that evokes vivid memories, and Orah, the intriguing elderly woman who knows its provenance, he is equally entranced by the drug's effect on him and the potential selling it has to send Faith to college. As his drug business increases, so do the complications in his life. He draws the unwanted attention of dangerous drug lords, falls in love with the daughter of a police officer, loses Faith's confidence, and sinks deeper into his own addiction. Hand to teens on the edge of new-adult readership who seek a gritty, twisting, high-stakes plot overlaid with pensive, well-crafted language."--Booklist Online.
