I thought my nightmare was over when my husband was arrested. I never imagined his mother would finish what he started.

​​​​​​​Seven months after her husband is jailed for attempted murder, Skyler Lawrence gives birth while battling crushing postpartum depression. When her wealthy mother-in-law, Eleanor, moves in to "help," Skyler is too desperate to refuse.

Eleanor is the perfect grandmother—nurturing Grace through the night, managing the house, always knowing what Skyler needs. But as the weeks pass, Skyler's mind unravels. Her memory fractures. Her depression deepens. One by one, she surrenders control—until she can't remember who she was without Eleanor.

When Skyler's friends Emma and Daniel begin to investigate, they uncover a horrifying secret: Eleanor has been drugging Skyler, carefully orchestrating her breakdown. Now, they must expose the truth before Eleanor's plan turns deadly.

But Eleanor is always one step ahead—and she's perfected this game over a lifetime.
