A perceptive story of how a young boy adjusts to the new man in his single mother"s life. "One can be lonely and One can be fun, and Two can be awful or perfect for some, and Three can be crowded or can be just right or even too many, you have to decide." One can have fun alone, thinks Everett Anderson. And when it"s just Everett and his mama-well, two is fine, too. But three . . . Everett tries to understand why Mama and Mr. Perry like to spend so much time together, although it"s hard, at first.
