The Only Survivors

From the publisher: "Seven hours in the past. Seven days in the present. Seven survivors remaining. Who would you save? A decade ago, two vans filled with high school seniors on a school service trip crashed into a Tennessee ravine—a tragedy that claimed the lives of multiple classmates and teachers. The nine students who managed to escape the river that night were irrevocably changed. A year later, after one of the survivors dies by suicide on the anniversary of the crash, the rest of them make a pact: to come together each year to commemorate that terrible night. Their annual meeting place, a house on the Outer Banks, has long been a refuge. But by the tenth anniversary, Cassidy Bent has worked to distance herself from the tragedy and from the other survivors. She’s changed her mobile number. She’s blocked the others’ email addresses. This year, she is determined to finally break ties once and for all. But on the day of the reunion, she receives a text with an obituary attached: another survivor is gone. Now they are seven—and Cassidy finds herself hurling back toward the group, wild with grief—and suspicion."
