Adrift in New York - Horatio Alger, Jr.

John Linden is a very wealthy man. The people who should inherit his property are his nephew, Curtis Waring, his niece Florence Linden, and his long lost son - if alive. John thinks it would be best if Florence and Curtis were married, and makes it a requirement if Florence wishes to have any of the property.
A boy named Dodger was sent to steal one of the wills of John Linden so that Curtis would inherit all the property. But Florence prevents Dodger from stealing, and they become friends… To the shock of her uncle and cousin, she decides to leave her uncle's house with Dodger instead of marrying Curtis. And what then? Would she be able to get used to being poor? And will she be poor for ever? Adrift in New York? (Summary by Stav Nisser)
