A teen who's taken on so many identities she's not sure who she is anymore stumbles across a secret with devastating implications in this riveting third book in Suzanne Young's New York Times bestselling Program series--now with a reimagined look.

In a world before The Program...

Quinlan McKee is a closer. Since the age of seven, Quinn has held the responsibility of providing closure to grieving families with a special skill--she can "become" anyone.

Recommended by grief counselors, Quinn is hired by families to take on the short-term role of a deceased loved one between the ages of fifteen and twenty. She's not an exact copy, of course, but she wears their clothes and changes her hair, studies them through pictures and videos, and soon, Quinn can act like them, smell like them... be them. But to do her job successfully, she can't get attached.

Now seventeen, Quinn is deft at recreating herself, sometimes confusing her own past with those of the people she's portrayed. When she's given her longest assignment, playing the role of Catalina Barnes, Quinn begins to bond with the deceased girl's boyfriend. But that's only the first of many complications, especially when Quinn finds out the truth about Catalina's death. And the epidemic it could start.
