The complicated marriage of the gifted Danish pianist Laurus Moss to the provincial American child of privilege Sydney Brant was a mystery to many who knew them, including their three children. Now, Eleanor, Monica, and Jimmy Moss have to decide how to divide or share what Laurus and Sydney have left them without losing one another.

Secure and cheerful Eleanor, the oldest, wants little for herself but much for her children. Monica, the least-loved middle child, brings her youthful scars to the table, as well as the baggage of a difficult marriage to the charismatic Norman, who left a brilliant legal career, though not his ambition, to become an Episcopal priest. Youngest and best-loved Jimmy, who made a train wreck of his young adulthood, has returned after a long period of alienation from the family surprisingly intact but extremely hard for his sisters to read.

Having lived through childhoods both materially blessed and emotionally difficult, with a father who could seem uninvolved and a mother who loved a good family game of "let's you and him fight," the Mosses have formed strong adult bonds that none of them wants to damage. But it's difficult to divide a beloved summer house three ways and keep it too. They all know what's at stake---in a world of atomized families, a house like Leeway Cottage can be the glue that keeps generations of cousins and grandchildren deeply connected to one another. But knowing it's important doesn't make it easy.
