Edward Barrett's grandmother committed suicide. She left him everything. Having been homeless, Edward unquestioningly moves into her apartment, unaware that she left something behind. Something that sinks its teeth into his very existence.

His one shot at figuring out what's haunting him and saving himself is inside the journals he picked up from Otherside Book Exchange – the writers were all victims, and all became monsters following their deaths.

Between the off-putting proprietor of Otherside – a soft-spoken woman named Conscience – and the distressing contents of the journals, Edward has no choice but to come around to the idea that otherworldly horrors exist, and they're all around him.

If he wants to save himself from being eaten alive, he needs to find the diary of the monster preying on him.
