Thirteen Storeys by Jonathan Sims

You're cordially invited to dinner. Penthouse access is available via the broken freight elevator. Black tie optional.

A dinner party is held in the penthouse of a multimillion-pound development. All the guests are strangers - even to their host, the billionaire owner of the building. None of them know why they were selected to receive his invitation. Whether privileged or deprived, besides a postcode, they share only one thing in common - they've all experienced a shocking disturbance within the building's walls.

By the end of the night, their host is dead, and none of the guests ever said what happened. His death remains one of the biggest unsolved mysteries - until now.

But are you ready for their stories?

Jonathan Sims' debut is a darkly twisted, genre-bending journey through one of the most innovative haunted houses you'll ever dare to enter.
