The Thorn Birds by Colleen McCullough

The Thorn Birds is a chronicle of three generations of Clearys—an indomitable clan of ranchers carving lives from a beautiful, hard land while contending with the bitterness, frailty, and secrets that penetrate their family. It is a poignant love story, a powerful epic of struggle and sacrifice, a celebration of individuality and spirit. Most of all, it is the story of the Clearys' only daughter, Meggie, and the haunted priest, Father Ralph de Bricassart—and the intense joining of two hearts and souls over a lifetime, a relationship that dangerously oversteps sacred boundaries of ethics and dogma.
