The Thorn Birds by Colleen McCullough

The Thorn Birds is a robust, romantic saga of a singular family, the Clearys. It begins in the early part of this century, when Paddy Cleary moves his wife, Fiona, and their seven children to Drogheda, the vast Australian sheep station owned by his autocratic and childless older sister; and it ends more than half a century later, when the only survivor of the third generation, the brilliant actress Justine O'Neill, sets a course of life and love halfway around the world from her roots.
