Mothers by Jax Peters Lowell

As a young boy, Willy knows only the warm, supportive, slightly off-beat world of his two mothers--Claire, a respected photographer, and Theo, a successful caterer. But Willy soon learns of another world in which his mothers are viewed with hatred and mistrust. When that world forces Claire and Theo to reexamine their lives, Willy is the only person who can prove to them and to the courts that 'normal' is in the eye of the beholder. A powerful debut novel.
