In a word: Superb. I adored this book. These smartass, tough-as-nails young men just get under your skin, and you end up laughing and crying with them (though they wouldn't admit to doing the latter).
Alvaro is a popular delinquent in what-might-be-called a reformatory school. He ends up rescuing Cande, a pretty boy, from punk thugs, and a bond forms between them. Alvaro and his friends, Kiki and Leo, form a dancing band, and with Cande and Elly they discover singing as well. Their goal is a competition a few weeks away. Together they become more than what the world, their parents, and their teachers expect, rising above their past crimes and grim view of the future.
The spirit of this story is breathtaking. It would be so easy to give up and let go, but these boys have a shared dream, and they pursue it regardless of what others think of their chances. What threw me in this book was the wonderful, exhilarating banter between all the boys, as well as the way the adults shape up too when they realize what these guys are capable of. The dreams of few affect so many it's just marvelous to witness.
This was a beautiful story. I simply cannot recommend it enough for the simple lessons that what you see isn't always what you get, and how easy it is to misjudge people based on their reputation, past, attitude, or appearance. The positive outlook here is very uplifting, and I found myself grinning from ear to ear at the successes of Party of Five. I highly recommend!
