After being uninvited from her son Nathan’s fortieth-birthday cruise so his wife Kayla could have “family only” aboard, Miriam calmly agrees, then spends the following days canceling every payment she’d secretly been funding, from the family car to the grandchildren’s school activities. While the cruise sails on, she sells the lake house Nathan always assumed would remain “the family home,” packing only what mattered and leaving everything else to the new owners, the Sutherlands.

When Nathan and Kayla return from their vacation expecting to walk back into the life and property they’d always taken for granted, they find the locks changed and a note on the door revealing exactly who the new owner is, a discovery that’s about to upend everything they believed was permanently theirs.
