From the bestselling author of In an Instant comes a heartrending story about the power of friendship during the most challenging moments in life.

It's been eight years since a tragic accident changed Mo Kaminski's and Chloe Miller's lives forever. Now in their midtwenties, they're sharing an apartment in San Francisco and navigating the normal challenges of early adulthood. Along with their roommate, Hazel, they are making their marks on the world--Mo revolutionizing the news with her media start-up, Hazel using her big brain to anticipate the future, and Chloe rescuing abandoned strays in the city.

But when Hazel disappears after being sexually assaulted, Mo's and Chloe's lives are again suddenly ripped apart. And when the perpetrator turns up drugged and beaten, the mystery of where Hazel is deepens. Intensely worried and desperate to discover the truth, they set out to find Hazel and bring her home.

Mo and Chloe are no strangers to tragedy, but this journey will test them in ways they never imagined. The stakes are high; the future uncertain; the need for justice essential.

Will their commitment to their friend bring them closer together--or ultimately drive them apart?
