A short beynika book!!
Serendipity - The effect by which one accidentally stumbles upon something truly wonderful , especially while looking for something entirely different.
Beyoncé and Onika meet on a train bound for New York. Both thought they'd never meet again, but just the opposite happens.
They become friends, but the feelings of one and the mental health of the other make it difficult for the two women to be together.
