To the Byrne children, constellations were more than stick figures in the night sky. At their father's telling, their myths became tales of adventure and romance for Percy, Allie, Mary and Aurie, whose names seem to imbue celestial royalty upon them. When the Orion River floods in 1965, the Byrne children are drawn to it like sailors to a siren's call. After Aurie disappears in the river, their names seem more like a curse. Though self-imposed, the curse follows them through three decades before each learns the key to breaking it – love, and forgiveness. But sometimes the hardest person to forgive is yourself.
