Windfall by Jennifer E. Smith

Alice buys a lottery ticket for her friend, Teddy's 18th birthday. What are the chances? But he wins! $140 million at that! As Teddy begins to explore life as a multi-millionaire, we see how he changes, and how his friendship with Alice changes.

I wasn't too happy with a part of the ending. It seemed a bit forced and contrived to me. Well, I guess I am always rooting for the underdog.

Overall, a unique and fast Young Adult read.
