A completely unforgettable story from the No.1 bestselling author of The Last List of Mabel Beaumont – perfect for fans of Taylor Jenkins Reid, Colleen Hoover, and Gabrielle Zevin.

You think you know what happened that day… But what if you’re wrong?

Everyone who was around in the 1990s remembers where they were when they heard that AJ Silver had died. In the summer of ’96, there was no avoiding the story that America's biggest teen pop sensation had plunged to his death on a rollercoaster at a family-run amusement park in rural England.

Now, 27 years have passed, and – even if you’re too young to recall the event – you’ve probably heard AJ Silver's songs topping the charts again. So what better time to take a forensic look at what happened that summer?

I’ve spent hundreds of hours interviewing everyone who was there that fateful day: workers, friends, family… the people who gained from his death, and the people who lost everything.

But you’re going to want to pay attention. Because I’ve found out a secret. One you’re all going to want to know… Perhaps it wasn’t such an accident after all?

A truly unique and unforgettable story, set in 1990s Los Angeles and rural England, with more twists and turns than a rollercoaster. You’ll be gripped!
