Rob is afraid of her eldest daughter. Callie collects tiny bones, whispers to imaginary friends and frightens her younger sister, Annie. In Callie, Rob recognises the same darkness that haunted the family and childhood she has spent years trying to escape.

Determined to protect Annie, Rob takes Callie to Sundial, the isolated home where she grew up deep in the Mojave Desert. There, Rob begins revealing disturbing secrets from her past—and Callie starts to fear that her mother has brought her to the desert for a reason neither of them will survive.

A brutal and unsettling modern gothic horror about motherhood, inherited violence and the terrifying question of whether monsters are born or made.
