Local author Brendan Ritchie has put four characters in that exact scenario in his new book Carousel.
Nox, Taylor, Lizzy and Rocky find themselves locked in Cannington�s giant centre for months as an apocalypse destroys the outside world.
�The book is set entirely within Carousel,� he said. �I was tempted to drive out there, wander around, take some photos and get really familiar with the place.
�But I wanted to experience Carousel with the characters.�
He said Australian authors had a long history with post-apocalyptic literature but Carousel was different.
�The shopping centre setting makes Carousel slightly different to other post-apocalyptic literature because the characters don�t have to fight for food or shelter,� he said. �There is an element of fantasy to having an entire shopping centre at their disposal and their battle for survival is more of an internal one.
�I think post apocalyptic stories will always pose interesting questions about where we are headed as a society and what we value.�
Carousel is available from Fremantle Press.
