On a Boston street one warm spring day after a long New England winter, Hazel and Remy spot each other for the first time in years. Under ordinary circumstances, this meeting might seem insignificant. But Remy, a gifted violinist, is married to the composer Nicholas Elko - once the love of Hazel's life. Over the decades, each has buried disappointments and betrayals that now threaten to undermine their happiness. But as their entwined stories unfold from 1987 to 2007, each will discover the surprising ways in which the quest to create something real and true, can lead to the most personal of revelations.
