A few months before graduating high school in 1985, Charli Crawford’s world came crashing to a halt with the death of her boyfriend. Everything changed that night – every plan, every dream, every possibility…

Now forty years later, Charli – an Army veteran and smalltown police chief in Northern Michigan – learns a couple of important things. The first is that the world around her – the entire planet – is on a collision course with destruction.

The second is that her old high school friend and tech millionaire – ‘Freaky’ Molly Foust – has created an app that would let Charli go back to that precious time, that time before, that time when everything seemed simpler and so full of hope and promise.

“It’s not WHERE we’re going, Charli – it’s when.’
