Spoiler:
By the author of The Psychoanalyst and Checkmate the Psychoanalyst.
When Maeve disappears without a trace, her daughter Sloane is not surprised: if her mother had to disappear, it could only be under strange circumstances. However, this time it is different: a few days after her mother's disappearance, Sloane receives a package that she herself has sent her, containing several thousand dollars, the deed to her house and a gun. There is also a note with the following words: Sell everything. Keep the gun. Practice. Run away. Now.
Just two weeks away from graduating as an architect and in the midst of this personal crossroads, Sloane receives a job offer from a mysterious millionaire who wants to build six memorials for six people who died, again, under strange circumstances. As Sloane investigates these deaths, her mother's advice becomes more and more present. Who can Sloane trust now? Will she have time to follow her mother's lead when she reaches the end of the maze her sinister employer has been creating?
