About this listen

Ava thought the great tragedy of her life would be getting stuck in a dead-end office job, but reality looks even grimmer when she goes on an ill-fated hike with two of her co-workers.

Meanwhile, spiralling after a disastrous falling-out with her mercurial best friend, Savannah retreats to her parents' empty lake house in upstate New York. Her days blur into a hazy swirl of clinically concerning overthinking and alcohol – until she chases her nightly bottle of wine with an Ambien and wakes in the woods behind her house next to a dead body.

Unfortunately, Savannah is so down bad that this well-preserved corpse offers some compelling friend potential; after all, a dead person can't judge you, they're great listeners and they're not going to leave.

Ava, it turns out, is more than just a cold, lonely corpse. She was funny. She was smart. And Savannah has finally found someone she can talk to.

Is Savannah finally losing her grip – or has she found what she's needed all along?
