Brewster’s Millions [EPUB ebook] 

Young Brewster inherits a million dollars from his grandfather. Soon afterwards, his rich uncle also dies, leaving him seven million dollars. His uncle, however, hated Brewster’s grandfather and places a condition on his will: Brewster has to spend every penny of his grandfather’s million in a year, without gaining any assets or goods. If he succeeds, he will inherit his uncle’s seven million. If not, he will be as penniless as he was before.
