Dave was 32 when he drove his car into Loch Lomond, shattered by finding your hidden letter three years after an illness took your life. He wanted to drown and join you.

But Dave carries a lifetime of devastating grief, your final letter in his pocket, and a fierce, terrifying obsession to rewrite your tragic fate this time.
