Two little girls, holding hands and singing in the back seat of a car. There for each other, unafraid. Life for the Stone girls is a life lived on the edge. Singing for a living, Marley and Andi find their way through a childhood of upheaval marked by their mother Donna's dark, unpredictable flights. Today, Marley writes the songs her twin, country diva Andi Stone, makes famous, and the girls' connection struggles to survive the cuts and devastations of fame. "You girls," laments their manager. "One of you marries indiscriminately, the other not at all." When without warning Donna Stone takes her own life, alone at the family cabin, danger stalks Marley back to Lost Prince Lake, back into the loves and betrayals of the past. Hidden truths threaten to take the Stone sisters down, singly and together. A powerful, intimate portrait of love, ambition, and survival, So Long As We're Together takes the reader into the lives of three women who give song to broken hearts, and for whom music is the language of family.
