Polly Prince is very free spirited. She went to school with Reuben for a while, but then her and her mom moved away. She admits that she moves around a lot, because she tends to get a little too stir-crazy in one place. When she met Reuben, she had been living in New York for about 4 months, but hadn't moved a thing in her apartment. She loves Salsa Dancing and was writing a Children's book. In the end, Reuben finds that Polly maybe the biggest risk of his life, but it would be worth it.
