Cannot say enough about this book -- loved it. But here's the publisher's blurb:
Meet the Rat: A dancing, football-playing gangster-baiting ten-year-old. When she foresaw her father's death, she picked up her football and decided to head for New York. Meet her older brother Bob: Protector of the Rat, but more often her follower, he is determined to find their uncle in America and discover a new life for them both. On their adventures across the flatlands of Winnipeg and through the exciting streets of New York, Bob and the Rat make friends with a hilarious con man and a famous rap star, and escape numerous dangers. But is their Uncle a rich business man, or is the word on the street, that he something more sinister, true? And will they ever find him? Hughes has created a funny, warm, unique world that lives and breathes. Like I Capture the Castle, Breakfast at Tiffany's, The Curious Incident, Hughes' story and characters will resonate for many and for years to come.
