Celeste Friedman is an award-winning singer who has tried marriage twice and has had many live-in boyfriends. Now she remains happily single, and she has written Single 101. When Cora Lonning’s parents divorced when she was 17, she held the divorce against her father for leaving her, deciding not to trust any men. But when she was 31, she talked with her father and learned his reasoning, which rewrote her history. Good thing. He died soon after.
