Sunny Cooper has been running since she was eighteen—from the New Mexican commune where she grew up . . . and from the haunting memory of the freak accident that took the life of her younger sister. Now, at thirty-two, Sunny voices radio spots in Albuquerque while struggling to hold on to a floundering relationship. But when a second tragic accident—and the devastating truths that come to light in its aftermath—turns her world upside down, Sunny runs again.

In the town of Harmony on San Miguel Island, she takes a new job, learns to ride a motorcycle, and makes some surprising new friends. But the past is never far behind. A startling discovery—along with an emotional and revelatory reunion with her estranged mother—is forcing Sunny to step out from the shadows of yesterday to embrace an uncertain future.
