The fabulous new novel from the bestselling author of Being Committed.

They were the best of friends, they were the worst of friends . . . Cassie and Lizbet are sisters. They are very different and believe they want different things in life. But just how different are they? Cassie's discovery that she's adopted has fuelled her desire to have a baby — the fact that she's having marital problems is an inconvenience she's choosing to ignore.

When her sister Lizbet — indifferent to children at the best of times — falls pregnant by mistake, the sisters' relationship is severely compromised. Lizbet, who doesn't know Cassie is adopted, cannot understand why Cassie isn't more pleased for her. Then, Lizbet miscarries and tries to come to terms with the trauma by concentrating on her career. She seems to be okay, but what is left is an overriding resentment towards her sister.

And when temptation takes them both away from their homes it is not only their own relationship that is challenged. At war, little do they realize they have more in common than they think . . .
