When Andi Lin overhears details about a harmful research study at the food corporation Nutrexo, she’s instantly worried that her dad is involved. He left home to participate in one of the company’s clinical trials, and was in frequent contact at first—but her recent attempts to reach him have been met with silence.

Fearing he may be in danger, Andi sets out to investigate. She finds an unlikely ally in her neighbor Cyrus, whose mother once worked for Nutrexo and is hiding secrets of her own. Their search for answers leads them to the head scientist at Nutrexo’s confidential research facility, where they learn that the truth is more complicated—and more devastating—than they ever could have imagined.

This captivating debut is at once a page-turning thriller, a contemporary coming-of-age story, and a thought-provoking look at the consequences of our desires for power, success, and control.

Several months after Nutrexo’s downfall, Andi plunges into a new mission: investigating a dietary supplement with unusual, potentially-dangerous side effects. Cyrus wants to help, but he’s hopelessly distracted by the painful secret he’s been hiding about his older brother. He can’t bring himself to tell anyone what really happened that night. Not even Andi.

Meanwhile, Roya is vacationing on a remote island when she makes a chilling discovery. A human skeleton—and near it, a rusty iron key. Can the mysterious girl Roya glimpsed on the bluffs help her piece together some answers? Or will she drag her down into the dark undercurrents flowing beneath them?

This sweeping sequel to When We Vanished takes the reader on a journey through time and place, from a 1970s island commune to a present-day corporate apple orchard, as it explores the question of just how far we’ll go to help the people we love.
