Here we follow Sarah, her elder sister left when she was in her teens, never to be seen again. It's decades later when she gets the call that her sister is dead, found on a compound, part of a cult, and leaves behind three children.
This is split into two timelines, one where we follow Sarah navigating these three ophaned children. The other, her elder sister and children in their cult life.
I was far more interested in the present day.
