Finn is a 17-year-old full of paradoxes.
He's a drug dealer, but he's scoring money to send his twin sister to Harvard. He's desperate to shoot up even though he's the most popular kid in Dammertown. He's a philosopher and orator who's failing all his classes. The only time he finds peace is when he's bird-watching.
When Finn's plan to get his sister out of D-Town for good falls apart, his life begins to spiral out of control - until he forms an unlikely bond with an old woman who might just be the answer to his troubles. She has access to a miracle drug Finn calls indigo, named for the beautiful blue color of the indigo bunting bird. When users take a hit of indigo, they experience their favorite memory with such intensity that they return to the present with a memento from the past. Finn is convinced that the drug is the way out of everything broken in his life. But is it really as magical as it seems?
