This was a brilliant 'locked room' mystery/thriller that completely turns what you think is going to happen on it's head. After the passing of their father three sibling find them selves in a house in the middle of no where along with their mother and some unexpected guest, they must stay their for 1 month to get a share of their mysterious fathers inheritance. What began as a standard thriller ended it unbelievable unexpected ways. With a disturbing undercurrent this book keeps you hanging on amidst the unease until the very end.

A great read for fans of the Wayward Pines Trilogy by Blake Crouch.
